Abstract The methods of sampling ambient air for organic compounds for subsequent analysis are discussed. The following methods of sample collection are presented and the advantages and disadvantages of each is given: concentration of component of interest on to solid sorbents, into liquid sorbents or on to filter-sorbent combinations; cryogenic concentration; derivatization of the component of interest; integrated sampling into containers such as canisters and bags; and direct analysis. Sampling problems of breakthrough of component of interest, formation of artifacts during sampling, and interferences from water collected from air during sampling are also discussed. The relative advantages of integrated sampling into containers versus concentrating on to sorbents and/or filters are presented.
