                       ELECTRONIC SENSOR TECHNOLOGY, INC.
                   Notes to Consolidated Financial Statements
                                   (Unaudited)
                               September 30, 2009

1)   Basis of Presentation

     The accompanying unaudited consolidated financial statements have been
     prepared in accordance with generally accepted accounting principles for
     interim financial statements and with the instructions to Form 10-Q and
     Item 10 of Regulation S-K. Accordingly, they do not include all the
     information and disclosures required for annual financial statements. These
     financial statements should be read in conjunction with the consolidated
     financial statements and related footnotes for the year ended December 31,
     2008, included in the Annual Report filed on Form 10-K for the year then
     ended.

     In the opinion of the management of Electronic Sensor Technology, Inc. (the
     "Company"), all adjustments (consisting of normal recurring accruals)
     necessary to present fairly the Company's financial position as of
     September 30, 2009, and the results of operations and cash flows for the
     nine month period ending September 30, 2009 have been included. The results
     of operations for the nine month period ended September 30, 2009 are not
     necessarily indicative of the results to be expected for the full year. For
     further information, refer to the consolidated financial statements and
     footnotes thereto included in the Company's Annual Report filed on Form
     10-K as filed with the Securities and Exchange Commission for the year
     ended December 31, 2008.

2)   Basis of Consolidation

     The accompanying financial statements include the accounts of the Company
     and its wholly owned subsidiaries. All intercompany balances and
     transactions have been eliminated in consolidation.

3)   Nature of Business and Summary of Significant Accounting Policies

     a)   Nature of Business

          The Company develops and manufactures electronic devices used for
          vapor analysis. It markets its products primarily to government
          agencies, higher education institutions, and multi-national
          corporations. The company sells its products directly to domestic
          customers who are end-users and, sells internationally to distributors
          who, in turn, sell to end-users. Distributors are used for their
          capability to provide local after-sales support to end-users.

     b)   Cash and Cash Equivalents

          The Company considers highly liquid financial instruments with
          maturities of three months or less at the time of purchase to be cash
          equivalents.

     c)   Certificate of Deposit - Restricted

          The Company had two certificates of deposit in place at September 30,
          2009. One, in the amount of $12,000, was used to secure and
          collateralize the Company's credit card liability. The other
          certificate of deposit in the amount of $3,500 was used to provide a
          performance guarantee for a sale to an overseas customer.

     d)   Allowance for Doubtful Accounts

          The allowance for doubtful accounts is based on the Company's
          assessment of the collectibility of customer accounts and the aging of
          the accounts receivable. If there is a deterioration of a major
          customer's credit worthiness or actual defaults are higher than the
          Company's historical experience, the Company's estimates of the
          recoverability of amounts due it could be adversely

                                       F-4

          affected. The Company regularly reviews the adequacy of the Company's
          allowance for doubtful accounts through identification of specific
          receivables where it is expected that payments will not be received.
          The Company also establishes an unallocated reserve that is applied to
          all amounts that are not specifically identified. In determining
          specific receivables where collections may not be received, the
          Company reviews past due receivables and gives consideration to prior
          collection history and changes in the customer's overall business
          condition. The allowance for doubtful accounts reflects the Company's
          best estimate as of the reporting dates. Changes may occur in the
          future, which may require the Company to reassess the collectibility
          of amounts and at which time the Company may need to provide
          additional allowances in excess of that currently provided.

          The allowance for doubtful accounts balance at September 30, 2009 was
          increased to $105,000 due to uncertainty in collection from a customer
          who has encountered financial difficulties.

     e)   Revenue Recognition

          The Company sells directly to domestic customers who are end-users.
          The Company sells internationally to distributors who, in turn, sell
          to end-users. Sales to distributors are not contingent on the sale by
          the distributor to an end-user. As such, the distributor is the owner
          of the products it purchases from the Company. The Company records
          revenue from sales of products to customers when the products are
          shipped, collection of the purchase price is probable and the Company
          has no significant further obligations to the customer. Costs of
          remaining insignificant Company obligations, if any, are accrued as
          costs of revenue at the time of revenue recognition. Cash payments
          received in advance of product shipment or service revenue are
          recorded as deferred revenue.

     f)   Shipping and Handling

          The Company accounts for shipping and handling costs as a component of
          "Cost of Sales".

     g)   Inventories

          Inventories are comprised of raw materials, work in process, and
          finished goods. Inventories are stated at the lower of cost or market
          and are determined using the first-in, first-out method.

     h)   Property and Equipment

          Property and equipment are stated at cost, net of accumulated
          depreciation. Depreciation is computed using the straight-line method
          over the estimated useful lives of five years.

     i)   Research and Development

          Research and development costs are charged to operations as incurred
          and consists primarily of salaries and related benefits, raw materials
          and supplies.

     j)   Use of Estimates

          The preparation of the financial statements in conformity with
          generally accepted accounting principles requires management to make
          estimates and assumptions that affect the reported amounts of assets
          and liabilities and disclosures of contingent assets and liabilities
          at the date of the financial statements and the recorded amounts of
          revenues and expenses during the reporting period. Actual results
          could differ from those estimates.

                                       F-5

     k)   Fair Value of Financial Instruments

          The fair value of certain financial instruments, including accounts
          receivable, accounts payable and accrued liabilities, approximate
          their carrying values due to the short maturity of these instruments.

          The fair value as of September 30, 2009 of the 9% convertible
          debentures issued by the Company on March 28, 2008 and the 9% note
          payable issued by the Company on April 10, 2009 amounts to $2,000,000
          and $1,000,000, respectively, based on the Company's incremental
          borrowing rate.

     l)   Long-lived Assets

          The Company reviews long-lived assets, such as property and equipment,
          to be held and used or disposed of, for impairment whenever events or
          changes in circumstances indicate that the carrying amount of an asset
          may not be recoverable. If the sum of the expected cash flows,
          undiscounted and without interest, is less than the carrying amount of
          the asset, an impairment loss is recognized as the amount by which the
          carrying amount of the asset exceeds its fair value. At September 30,
          2009 no assets were impaired.

     m)   Capital Lease

          On June 28, 2007, the Company entered into a capital lease under which
          the present value of the minimum lease payments amounted to $59,200.
          The present value of the minimum lease payments was calculated using a
          discount rate of 11.41%. The principal balance of the capital lease
          obligation amounted to approximately $21,800 at September 30, 2009.
          The capital lease matures on September 8, 2010.

     n)   Basic and Diluted Earnings Per Share

          Basic earnings per share are calculated by dividing income available
          to stockholders by the weighted-average number of common shares
          outstanding during each period. Diluted earnings per share are
          computed by dividing income available to stockholders, adjusted for
          interest savings on the convertible debenture and changes in income or
          loss associated with the derivative contract that would result if the
          contract had been recorded as an equity instrument for accounting
          purposes during the period, by the weighted average number of common
          shares outstanding during the period plus the net effect of stock
          options and warrants, effect of the convertible debentures, and
          embedded conversion features.

          The outstanding options, warrants and shares equivalent issuable
          pursuant to embedded conversion features and warrants at September 30,
          2009 and 2008 are excluded from the loss per share computation for
          that period due to their antidilutive effect.

          The following sets forth the computation of basic and diluted earnings
          per share at September 30:

     o)   Stock Based Compensation

          The Company adopted guidance for "Share Based Payments." The guidance
          requires companies to expense the value of employee stock options and
          similar awards and applies to all outstanding and vested stock-based
          awards.

          In computing the impact, the fair value of each option is estimated on
          the date of grant based on the Black-Scholes options-pricing model
          utilizing certain assumptions for a risk free interest rate;
          volatility; and expected remaining lives of the awards. The
          assumptions used in calculating the fair value of share-based payment
          awards represent management's best estimates, but these estimates
          involve inherent uncertainties and the application of management
          judgment. As a result, if factors change and the Company uses
          different assumptions, the Company's stock-based compensation expense
          could be materially different in the future. In addition, the Company
          is required to estimate the expected forfeiture rate and only
          recognize expense for those shares expected to vest. In estimating the
          Company's forfeiture rate, the Company analyzed its historical
          forfeiture rate, the remaining lives of unvested options, and the
          amount of vested options as a percentage of total options outstanding.
          If the Company's actual forfeiture rate is materially different from
          its estimate, or if the Company reevaluates the forfeiture rate in the
          future, the stock-based compensation expense could be significantly
          different from what we have recorded in the current period. The impact
          of applying this guidance approximated $14,300 in additional
          compensation expense during for the nine month period ended September
          30, 2009. Such amount is included in general and administrative
          expenses on the statement of operations.

     p)   Risk Factors

          Recently, the credit markets and the financial services industry have
          been experiencing a period of unprecedented turmoil and upheaval
          characterized by the bankruptcy, failure, collapse or sale of various
          financial institutions and an unprecedented level of intervention from
          the United States federal government. While the ultimate outcome of
          these events cannot be predicted, they may have a material adverse
          effect on the Company's liquidity and financial condition if its
          ability to borrow money to finance its operations from its existing
          lenders or from other sources, or obtain credit from trade creditors
          were to be impaired. In addition, the recent economic crisis could
          also adversely impact our customers' ability to finance the purchase
          of electronic instruments from us or our suppliers' ability to provide
          us with product, either of which may negatively impact the Company's
          business and results of operations.

                                       F-7

          Concentration of Credit Risks

          The Company is subject to concentrations of credit risk primarily from
          cash and cash equivalents. The Company's cash and cash equivalents
          accounts are held at financial institutions and are insured by the
          Federal Deposit Insurance Corporation ("FDIC") up to $250,000 at
          September 30, 2009. During the nine-month periods ended September 30,
          2009 and 2008, the Company has reached bank balances exceeding the
          FDIC insurance limit. While the Company periodically evaluates the
          credit quality of the financial institutions in which it holds
          deposits, it cannot reasonably alleviate the risk associated with the
          sudden failure of such financial institutions.

          Customer Concentration

          The Company's largest customer accounted for approximately 15% and 26%
          of its revenues during the nine-month periods ended September 30, 2009
          and 2008, respectively. The customer accounted for approximately 39%
          and 53% of the gross accounts receivable balance at September 30, 2009
          and 2008, respectively.

          Product Concentration

          All of the Company's revenues were derived from the sale of electronic
          devices, related accessories and support services used for vapor
          analysis.

          Geographic Concentration

          The Company sells its products internationally in 20 countries. Sales
          to these countries were approximately 44% and 43% of net revenues
          during the nine-month periods ended September 30, 2009 and 2008,
          respectively.

     q)   Recently Issued Accounting Pronouncements

          In April 2009, the FASB issued guidance in the Financial Instruments
          Topic of the Codification on interim disclosures about fair value of
          financial instruments. The guidance requires disclosures about the
          fair value of financial instruments for both interim reporting
          periods, as well as annual reporting periods. The guidance is
          effective for all interim and annual reporting periods ending after
          June 15, 2009 and shall be applied prospectively. The adoption of this
          guidance had no impact on our financial statements as of September 30,
          2009.

          In May 2009, the FASB issued guidance in the Subsequent Events Topic
          of the Codification . The guidance is intended to establish general
          standards of accounting for, and disclosure of, events that occur
          after the balance sheet date but before financial statements are
          issued. It requires the disclosure of the date through which an entity
          has evaluated subsequent events and the basis for that date. The
          guidance is effective for interim or annual financial periods ending
          after June 15, 2009 and is required to be adopted prospectively. We
          adopted this guidance effective for the quarter ending June 30, 2009.
          The adoption of this guidance had no impact on our financial
          statements as of September 30, 2009.

          In June 2009, the FASB issued guidance which will amend the
          Consolidation Topic of the Codification. The guidance addresses the
          effects of eliminating the qualifying special-purpose entity (QSPE)
          concept and responds to concerns over the transparency of enterprises'
          involvement with variable interest entities (VIEs). The guidance is
          effective beginning on January 1, 2010. We do not expect the adoption
          of this guidance to have an impact on our financial statements.

          In August 2009, the FASB issued Accounting Standards Update No.
          2009-05, "Measuring Liabilities at Fair Value" (ASU 2009-05). ASU
          2009-05 amends the Fair Value Measurements and Disclosures Topic of
          the FASB Accounting Standards Codification by providing additional
          guidance clarifying the measurement of liabilities at fair value. ASU
          2009-05 is effective for us

                                       F-8

          for the reporting period ending December 31, 2009. We do not expect
          the adoption of ASU 2009-05 to have an impact on our financial
          statements.

4)   Convertible Debentures Issued To Related Parties

     9% Debenture Payable

     On April 10, 2009, the Company received $1 million from Halfmoon Bay
     Capital Ltd., the Company's largest shareholder, in exchange for a
     debenture bearing an interest rate of 9% with a maturity of one year. The
     debenture grants the investor a security interest in all of the
     intellectual property of the Company.

     9% Convertible Debentures

     On March 28, 2008, we received $2,000,000 from Halfmoon Bay Capital Ltd.,
     the Company's largest shareholder, in exchange for a convertible debenture
     bearing an interest rate of 9%, payable semi-annually in cash. The
     convertible debenture has a five (5)-year term, and the conversion rate of
     the debenture is $0.0486 (equal to 41,152,263 common shares). The
     difference between the conversion rate of the debenture and the closing
     price of the Company's common stock on the date of issuance resulted in a
     note discount of approximately $58,000. The note discount will be amortized
     over the term of the convertible debenture. On October 5, 2009, Halfmoon
     Bay Capital Ltd agreed to defer a $90,000 interest payment owed to it on
     September 28, 2009 until December 31, 2009.

5)   Stockholders' Equity

     Common Stock

     On June 12, 2009, the Company filed Amended and Restated Articles of
     Incorporation with the Nevada Secretary of State. The Articles of
     Incorporation of the Company were amended and restated to give effect to
     the following amendments: (i) to increase the number of authorized shares
     of common stock from 200,000,000 shares to 250,000,000 shares, (ii) to vest
     authority in the Board of Directors to prescribe the classes, series and
     the number of each class or series of preferred stock and the voting
     powers, designations, preferences, limitations, restrictions and relative
     rights granted to or imposed upon any wholly unissued series of preferred
     stock and (iii) to clarify and restate that the purpose of the business of
     the Company is to engage in any lawful act or activity for which
     corporations may be organized under the General Corporation Law of the
     State of Nevada.

     Options

     In 2005, the Board of Directors adopted the Electronic Sensor Technology,
     Inc. 2005 Stock Incentive Plan. The purpose of the Stock Incentive Plan is
     to attract and retain the services of experienced and knowledgeable
     individuals to serve as our employees, consultants and directors. On the
     date the Stock Incentive Plan was adopted, the total number of shares of
     common stock subject to it was 5,000,000. The Stock Incentive Plan is
     currently administered by the Board of Directors, and may be administered
     by any Committee authorized by the Board of Directors, so long as any such
     Committee is made up of Non-Employee Directors, as that term is defined in
     Rule 16(b)-3(b) of the Securities Exchange Act of 1934.

     The Stock Incentive Plan is divided into two separate equity programs: the
     Discretionary Option Grant Program and the Stock Issuance Program. Under
     the Discretionary Option Grant Program, eligible persons may, at the
     discretion of the administrator, be granted options to purchase shares of
     common stock and stock appreciation rights. Under the Stock Issuance
     Program, eligible persons may, at the discretion of the administrator, be
     issued shares of common stock directly, either through the immediate
     purchase of such shares or as a bonus for services rendered for Electronic
     Sensor Technology (or a parent or subsidiary of Electronic Sensor
     Technology).

     Pursuant to the terms of the Discretionary Option Grant Program, the
     exercise price per share is fixed by the administrator, but may not be less
     than 85% of the fair market value of the common stock on the date of

                                       F-9

     grant, unless the recipient of a grant owns 10% or more of Electronic
     Sensor Technology's common stock, in which case the exercise price of the
     option must not be less than 110% of the fair market value. An option grant
     may be subject to vesting conditions. Options may be exercised in cash,
     with shares of the common stock of Electronic Sensor Technology already
     owned by the person or through a special sale and remittance procedure,
     provided that all applicable laws relating to the regulation and sale of
     securities have been complied with. This special sale and remittance
     procedure involves the optionee concurrently providing irrevocable written
     instructions to: (i) a designated brokerage firm to effect the immediate
     sale of the purchased shares and remit to Electronic Sensor Technology, out
     of the sale proceeds available on the settlement date, sufficient funds to
     cover the aggregate exercise price payable for the purchased shares plus
     all applicable federal, state and local income and employment taxes
     required to be withheld by Electronic Sensor Technology by reason of such
     exercise and (ii) Electronic Sensor Technology to deliver the certificates
     for the purchased shares directly to such brokerage firm in order to
     complete the sale. The term of an option granted pursuant to the
     Discretionary Option Grant Program may not be more than 10 years.

     The Discretionary Option Grant Program also allows for the granting of
     Incentive Options to purchase common stock, which may only be granted to
     employees, and are subject to certain dollar limitations. Any options
     granted under the Discretionary Option Grant Program that are not Incentive
     Options are considered Non-Statutory Options and are governed by the
     aforementioned terms. The exercise price of an Incentive Option must be no
     less than 100% of the fair market value of the common stock on the date of
     grant, unless the recipient of an award owns 10% or more of Electronic
     Sensor Technology's common stock, in which case the exercise price of an
     incentive stock option must not be less than 110% of the fair market value.
     The term of an Incentive Option granted may not be more than five years if
     the option is granted to a recipient who owns 10% or more of Electronic
     Sensor Technology's common stock, or 10 years for all other recipients of
     Incentive Options. Incentive Options are otherwise governed by the general
     terms of the Discretionary Option Grant Program.

     Pursuant to the terms of the Stock Issuance Program, the purchase price per
     share of common stock issued is fixed by the administrator, but may not be
     less than 85% of the fair market value of the common stock on the issuance
     date, unless the recipient of a such common stock owns 10% or more of
     Electronic Sensor Technology's common stock, in which case the purchase
     price must not be less than 100% of the fair market value. Common stock may
     be issued in exchange for cash or past services rendered to Electronic
     Sensor Technology (or any parent or subsidiary of Electronic Sensor
     Technology). Common stock issued may be fully and immediately vested upon
     issuance or may vest in one or more installments, at the discretion of the
     administrator.

     Management used Black Scholes methodology to determine the fair value of
     the options on the date of issue based on the following assumptions. The
     expected volatility was based on the average historical volatility of
     comparable publicly-traded companies.

                                                      2009             2008

          Exercise price                          $0.02 - $0.24    $0.03 - $0.24

          Expected dividend yield                       0%              0%
          Expected volatility                       36% - 47%       36% - 39%
          Risk free interest rate                 3.81% - 4.54%    4.01% - 4.54%
          Expected life of option                    5 years          5 years

     The fair value of the granted stock options shares was approximately $0.02
     per share. Approximately $30,600 and $14,300 were charged to compensation
     expense for the nine month period ended September 30, 2008 and 2009,
     respectively. The remaining amount will be amortized to compensation
     expense over future periods based on the vesting schedule of the respective
     stock option shares. The total compensation cost related to nonvested
     awards not yet recognized amounted to approximately $22,100 at September
     30, 2009. This compensation cost will be recognized over the weighted
     average period 2.3 years, unless the options are terminated sooner.

Item 2.  Management's Discussion and Analysis or Plan of Operation.

You should read the following discussion and analysis of our financial condition
and results of operations together with our interim financial statements and the
related notes appearing at the beginning of this report. The interim financial
statements and this Management's Discussion and Analysis of Financial Condition
and Results of Operations should be read in conjunction with the financial
statements and notes thereto for the year ended December 31, 2008 and the
related Management's Discussion and Analysis of Financial Condition and Results
of Operations, both of which are contained in our Annual Report on Form 10-K
filed with the Securities and Exchange Commission.

--------------------------------------------------------------------------------

Overview

The company is engaged in the development, manufacturing, and sales of a
patented product called zNose(R); a device designed to detect and analyze
chemical odors and vapors, or, in other words, an electronic "nose." We believe
the zNose(R) is superior to other electronic "noses" because of its speed,
specificity and sensitivity. The zNose(R) is capable of measuring and
quantifying the chemistry of any compound, fragrance, vapor or odor with parts
per trillion sensitivity in 10 seconds. We also believe the zNose(R) has the
unique ability to quantify and speciate the subject chemical vapor by creating
visual olfactory images. This enables the measured odor or vapor to be easily
identified by the user.

We believe that our products will have broad applications in the homeland
security, analytical instrumentation/quality control, and environmental
monitoring and detection markets. The company is involved in ongoing product
research and development efforts in that regard. The company has also
concentrated its efforts on further product development, testing and proving and
continuing to expand our sales and support organization.

The company was originally incorporated under the laws of the state of Nevada as
"Bluestone Ventures, Inc." on July 12, 2000. From inception until February 1,
2005, we engaged in the business of acquiring, exploring and developing certain
mining properties in Ontario, Canada. Upon acquisition of Electronic Sensor
Technology, L.P. ("ELP"), we abandoned our mining business and adopted ELP's
business of developing, manufacturing and selling the vapor analysis device. On
January 26, 2005, we changed our name to "Electronic Sensor Technology, Inc."

Our executive offices are located at 1077 Business Center Circle, Newbury Park,
California 91320 and our telephone number is (805) 480-1994.

Critical Accounting Policies

The company sells directly to domestic customers who are end-users. The company
sells internationally to distributors who, in turn, sell to end-users. Sales to
distributors are not contingent on the sale by the distributor to an end-user.
The distributor is the owner whether or not it sells the product to an end-user.
The company records revenue from sales of products to customers when the
products are shipped, collection of the purchase price is probable and the
company has no significant further obligations to the customer. Costs of
remaining insignificant company obligations, if any, are accrued as costs of
revenue at the time of revenue recognition. Cash payments received in advance of
product shipment or service revenue are recorded as deferred revenue. The
preparation of the financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosures of
contingent assets and liabilities at the date of the financial statements and
the recorded amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

The company reviews long-lived assets, such as property and equipment, to be
held and used or disposed of, for impairment whenever events or changes in
circumstances indicate that the carrying amount of an asset may not be
recoverable. If the sum of the expected cash flows, undiscounted and without
interest, is less than the carrying amount of the asset, an impairment loss is
recognized as the amount by which the carrying amount of the asset exceeds its
fair value. At September 30, 2009 no assets were impaired.

                                       2

Plan of Operations

Over the course of the next 12 months, we intend to execute our business plan
and focus our business development efforts in the following key areas:

o    By diversifying our product offerings to enhance the usefulness of our
     solutions for customers who will have already adopted one or more products;

o    By enhancing our product lines and developing new products to attract new
     customers; and

o    By developing partnering relationships with wide-ranging sales and
     distribution channel leaders already serving our vertical market space in a
     way that assists them in developing new revenue streams and opportunities
     through improved technical and sales support and customer services.

Nine Months Ended September 30, 2009 Compared to Nine Months Ended September 30,
2008

Revenues are derived from product sales and product support services. For the
three and nine month periods ended September 30, 2009, revenues were $194,700
and $778,100, compared to $543,900 and $1,303,600 in 2008. The decrease in
revenues for both the quarter and year-to-date results from: (1) a price
reduction averaging 24% on all of our instruments instituted at the beginning of
the year to make our products more price competitive and, (2) current global
economic conditions which have had a significant negative impact on the durable
equipment market. Potential customers are taking a "wait and see" approach to
capital equipment purchase decisions and are delaying such decisions until
economic conditions improve. This is reflected in the shipments for the quarter
and year-to-date which were 7 and 30 units, respectively, compared to 20 and 42
units shipped for the same periods in 2008. The decrease in shipments has also
impacted product support revenues which for the three and nine periods ended
September 30, 2009 were 16% and 50% less than for the same periods in 2008. The
decrease in product support revenues for the quarter was offset somewhat by an
increase in revenues from equipment rentals. Finally, revenues from the
company's license agreement with a customer ended in October 2008 when the
agreement was concluded and not renewed. The license agreement provided $12,500
in quarterly royalty income in 2008 for the company.

The company anticipates the stresses of current global economic conditions on
the commercial durable equipment market to continue for the rest of the year and
into 2010. These conditions have caused many of our customers (and potential
customers) to postpone their purchases of capital equipment. Until global
economic conditions improve, we expect the commercial durable equipment market
to remain depressed.

During the third quarter, we continued with the global rollout of our latest
product, the Model 4500, to mostly homeland security customers. Although the
upside potential of this market is vast, the homeland security market is
characterized by its long sales cycle where the time between product
introduction to product sale may be

                                       3

considerable. Initial market reaction to the Model 4500 has been positive and we
are confident in the product's capabilities to meet the requirements of our
homeland security customers. We are, however, still in the early stages of the
sales cycle with many of these customers and, as such, anticipate only modest
sales performance for the Model 4500 for the remainder of 2009.

Cost of Sales consist of product costs and expenses associated with product
support services. For the three and nine month periods ended September 30, 2009,
cost of sales were $130,300 and $459,100, compared to $367,800 and $828,500 in
2008. For the same periods, cost of sales, as a percentage of revenues, were 67%
and 59%, versus 68% and 64% in 2008. Cost of sales were improved by favorable
price economics on purchased materials which offset production variances
resulting from under-absorption of overhead expenses caused by reduction in
production levels due to business conditions and to work-off on-hand
inventories.

Gross profits were 33% and 41% of sales for the three and nine month periods
ended September 30, compared to 32% and 36% of sales for the same periods in
2008. Gross margins were aided by cost improvements, primarily price economics
achieved on purchased materials, on our products which offset an averaged 24%
across-the-board price reduction on our entire instrument product line
instituted at the beginning of the year.

Research and Development costs for the three and nine month periods ended
September 30, 2009 were $95,000 and $293,100 versus $163,900 and $512,900 for
the same periods in 2008. The improvement of $68,900 for the quarter is
attributed to lower personnel expenses due to reduction of census ($59,800),
lower operating expenses ($16,200), offset by an increase in facilities expenses
($7,100). For the nine month period, expenses were improved by $219,800 due to
reductions in personnel expenses ($206,500), lower operating expenses ($43,500),
offset by higher facilities expenses ($21,200) and increase in use of outsider
services ($9,000).

Selling, General and Administrative expenses for the three and nine month
periods ended September 30, 2009 were $485,400 and $1,490,800, compared to
$405,000 and $1,545,700 for the same periods in 2008. For the quarter, expenses
were $80,400 higher than in 2008 due to recognition of bad debts expense
($105,000), higher outside services expenses ($27,100), higher facilities costs
($3,900), offset by savings from reductions in personnel expenses ($26,500) and
operating costs ($29,100). For the nine month period, selling, general and
administrative expenses were $54,900 improved over the same period in 2008 due
to lower operating ($154,900) and personnel ($200,000) expenses, offset by
increase in bad debts expense ($105,000), higher outside services ($83,200) and
facilities ($111,800) costs,

Interest expense for the nine months ending September 30, 2009 was $4,400, as
compared to $740,400 for the same period in 2008. Interest expense for the first
nine months of 2008 consisted of: (1) interest accrued on the $7.0 million 8%
convertible debentures which were retired on March 28, 2008; and, (2)
amortization of the debt discount on the same retired 8% convertible debentures.

Interest expense - related party for the three and nine month periods ended
September 30, 2009 were $70,400 and $186,300, compared to $47,800 and $96,800
for the same periods in 2008. Current year's interest consists of interest
accrued on the $2.0 million 9% convertible debenture issued to Halfmoon Bay
Capital Ltd on March 28, 2008 and on the $1.0 million 9% debenture also issued
to Halfmoon Bay Capital Ltd on April 10, 2009. Interest expense for 2008
pertained only to the $2.0 million 9% convertible debenture issued on March 28,
2008.

Other income-derivatives. There was no income from derivatives in 2009. Such
income from derivatives in 2008 resulted primarily from the decrease in the fair
value of derivative liabilities between the measurement dates which are the
balance sheet dates. On March 31, 2008, we satisfied our obligations under the
8% convertible debentures and as a result, the company asserted that it has a
sufficient amount of authorized and unissued shares to settle its obligations
which can be settled in shares. Accordingly, the company reclassified all
contracts, warrants, and other convertible instruments outstanding at March 31,
2008 from liability to equity.

Gain on extinguishment of debt. In 2008, a gain was realized from the early
retirement of the 8% convertible debentures on March 31, 2008. There have been
no debt retirements in 2009.

                                       4

Liquidity and Capital Resources

For the nine months ending September 30, net cash used by the company for
operating activities were $1,165,600 and $1,510,600 for 2009 and 2008
respectively. Cash used for the nine months ending September 30, 2009 was
comprised of the net loss for the period of $1,656,600, plus net non-cash items
(including depreciation and amortization expenses of $32,400, increase in
allowance for doubtful accounts of $105,000, stock based compensation of
$14,300, issuance of common shares for services of $109,200 and amortization of
debt discount of $8,600) of $269,500, and plus the net change in operating
assets and liabilities of $221,500. Cash used in operations during the same nine
months of 2008 was comprised of the net loss for the period of $835,600, less
net non-cash expenses (including depreciation and amortization expenses of
$36,200, stock based compensation of $30,600, issuance of common shares for
payment of interest of $280,000, amortization of debt discount of $589,100,
amortization of deferred financing costs of $45,400, less decrease in fair value
of derivative liability of $323,200, and gain on early retirement of debt of
$1,261,900) of $603,800, and less the net change in operating assets and
liabilities of $71,200.

Investing activities used cash of 23,200 in the first nine months of 2009 and
provided cash of $6,300 during the same period in 2008. For the period, cash of
$4,800 was provided from the sale of property and equipment, and $28,000 was
used to purchase capital equipment. In 2008, cash of $9,900 was provided from
the sales of property and equipment and $3,600 was used to purchase capital
equipment.

Financing activities for the first nine months of 2009 provided cash of $985,200
which resulted from the issuance of a 9% debenture payable to an investor for
$1,000,000 and a decrease in capital lease obligation of $14,800. For the same
period in 2008, financing activities provided cash of $1,985,200 which included
$2,000,000 received from the issuance of 9% convertible debentures to a related
party investor, $3,500,000 from the issuance of equity to the same investor,
less $3,500,000 used to retire the 8% convertible debentures and a decrease in
capital lease obligation of $14,800.

On September 30, 2009 the company's cash (including cash equivalents) was
$208,400, compared to $484,000 on September 30, 2008. The company had working
deficit of $503,500 on September 30, 2009, compared to a working capital of
$1,414,000 on September 30, 2008.

The Company's current cash balance is not expected to be adequate to fund
operations beyond the fourth quarter of 2009. As such, the Company is actively
seeking additional funding to provide necessary working capital for operations
and implementation of its business strategy of creating a sales and marketing
staff for the marketing, advertising and selling of the zNose(R) family of
chemical detection products, increasing distribution channels both in the U.S.
and foreign countries, introducing new products, improving existing product
lines and development of a strong corporate infrastructure. There can be no
assurance that any financing will be available through any bank borrowings,
debt, or equity offerings, or otherwise, on acceptable terms. If future
financing requirements are satisfied through the issuance of equity securities,
investors may experience significant dilution in the net book value per share of
common stock and there is no guarantee that a market will exist for the sale of
the Company's shares.

Seasonality and Quarterly Results

We have not experienced and do not foresee any seasonality to our revenues or
our results of operations.

Inflation

Although we currently use a limited number of sources for most of the supplies
and services that we use in the manufacturing of our vapor detection and
analysis technology, our raw materials and finished products are sourced from
cost-competitive industries. While prices for our raw materials may vary
significantly based on market trends, we have not experienced and do not foresee
any material inflationary trends for our product sources.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements.

Item 3.  Quantitative and Qualitative Disclosures About Market Risk.

This Item is not applicable to smaller reporting companies.

Item 4T.  Controls and Procedures.

The company's Chief Executive Officer and Chief Financial Officer, after
evaluating the effectiveness of the company's disclosure controls and procedures
(as defined in Rules 13a-15(e) under the Securities Exchange Act of 1934, as
amended) as of the end of the period covered by this quarterly report on Form
10-Q, have concluded that, based on such evaluation, the company's disclosure
controls and procedures were effective to ensure that material information
relating to the company is recorded, processed, summarized, and reported in a
timely matter. In designing and evaluating the disclosure controls and
procedures, the company's management recognized that any controls and
procedures, no matter how well designed and operated, can provide only
reasonable assurance of achieving the desired control objectives, and the
company's management necessarily was required to apply its judgment in
evaluating the cost-benefit relationship of possible controls and procedures.

There were no changes in the company's internal control over financial reporting
that occurred during the period covered by this quarterly report that have
materially affected, or are reasonably likely to materially affect, the
company's internal control over financial reporting.
