Abstract

Selected volatile organic species, including chloroform, 1,2-dichloroethane, 1,1,1-trichloroethane, benzene, carbon tetrachloride, trichloroethylene, tetrachloroethylene, p-dichloro-benzene, o-dichlorobenzene, and nitrobenzene, are determined in ambient air by collection and concentration on Tenax-filled traps. The samples are recovered for analysis by a novel thermal desorption system which allows the injection of an aliquot of the sample into a 50M fused silica methyl silicone gas chromatographic column, which is programmed from -90° to 140° C. A standard addition process for qualitative analysis and an external standard method for quantitation are described, both using compressed gas standards. GC/MS is used for confirmation of sample identity on approximately 10% of the samples. © 1982, Taylor & Francis Group, LLC. All rights reserved.
