Abstract
A carefully designed study was conducted during the summer of 1998 to simultaneously collect samples of abmient air using two canisters from two commercial vendors and compare the analysis results to direct sorbent preconcentration results taken at the time of sample collection. A total of 32 1-h sample sets were taken, each composed of a 'real-time' sample analyzed by an autoGC/MS and two types of canisters, SUMMA and Silco. Hourly total non-methane organic carbon (TNMOC) ozone, and meteorological measurements were also made. Each of the canisters was analyzed on the autoGC/MS system for a target list of 108 VOCs and on a manual cryosampling GC/FID system. Comparisons are made between the collection and analysis methods. Because of the low sample loading (150-250 ppbC TNMOC), these comparisons are a stringest test of sample collection and analysis capabilities.
