Abstract
Research Triangle Institute (RTI) has recently evaluated several sampling devices for the collection of selected volatile and toxic organic compounds and have shown the stainless steel canister to be the best overall for whole-air sampling. The toxic organics collected in the canisters were analyzed using a automated cryogenic preconcentration followed by gas chromatography with a selective detector. Stability studies of selected organics in a passivated “SUMMA” stainless steel canister revealed that the compounds are stable over a 2-week period. The design of the sample collection system, collection and analysis procedures and stability data were described.
