2、riginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method standard describes a procedure for sampling

3、 and analysis of selected volatile organic compounds (VOCs)in ambient, indoor, orand workplace atmospheres. The test method is based on the collection of whole air samples in stainless steelcanisters with specially treated (passivated) interior surfaces. For sample analysis, a portion of the sample

4、is subsequently removedfrom the canister and the collected VOCs are selectively concentrated by adsorption or condensation onto a trap, subsequentlyreleased by thermal desorption, separated by gas chromatography, and measured by a mass spectrometric detector or otherdetector(s). This test method des

5、cribes procedures for sampling into canisters to final pressures both above and below atmosphericpressure (respectively referred to as pressurized and subatmospheric pressure sampling).21.2 This test method is applicable to specific VOCs that have been tested and determined to be stable when stored

6、in canisters.Numerous compounds, many of which are chlorinated VOCs, have been successfully tested for storage stability in pressurizedcanisters (1-4).3 Although not as extensive, documentation Documentation is also available demonstrating stability of VOCs insubatmospheric pressure canisters. While

7、 initial studies were concentrated on non-polar VOCs, information on storage stability hasbeen extended to Information on storage stability is available for many polar compounds as well (5-7).1.3 The procedure for collecting the sample involves the use of inlet lines and lines, air filters, flow rat

8、e regulators for obtainingtime-integrated samples, and in the case of pressurized samples, an air pump. Canister Typical long-term fixed location canistersamplers have been designed to automatically start and stop the sample collection process using electronically actuated valves andtimers (8-10). T

9、emporary or short-term canister samplers may require the user to manually start and stop sample collection. Aweatherproof shelter is may be required if the sampler is to be usedused outdoors. For the purposes of this test method, refer toPractice D1357 outside. for practices and planning ambient sam

10、pling events.1.4 The organic compounds that have been successfully measured at single-digit parts-per-billion by volume (ppbv) levels withthis test method are listed in Table 1. ThisThe test method is applicable to VOC concentrations ranging from the detection limitto approximately 300 ppbv. Above t

11、his concentration, samples require dilution smaller sample aliquots of sample gas may beanalyzed or samples can be diluted with dry ultra-high-purity nitrogen or air.1.5 The values stated in SI units are to be regarded as standard.
