This method describes the sample collection and analysis of vinyl acetate. Samples are collected by drawing known volumes of air through Ambersorb XE-347 sampling tubes. Following desorption with 1 mL of 95/5 (v/v) methylene chloride/methanol the samples are analyzed by gas chromatography with flame ionization detection (FID). Upon receipt at the laboratory the sampling tubes should be stored at refrigerated temperature until analyzed.
