Analytical methods and instrumentation for collecting and analyzing hazardous vapor-phase organics occurring in ambient air were developed and evaluated. The areas of investigation included (a) the evaluation of Tenax GC sorbent for variations in the breakthrough volumes for different lots; (b) studies on in situ reactions which might occur during the collection of organic vapors from ambient air; (c) evaluation of a permeation system for delivering precise quantities of organic vapors for calibrating instruments; (d) development of software programs for quantification of volatile organics using high resolution gas chromatography/mass spectrometry/computer (hrgc/ms/comp); (e) determination of relative molar response factors (RMR) for quantitative hrgc/ms/comp analysis; and (f) the identification and quantification of organic pollutants in ambient air from several geographical areas within the Continental U.S.
