Abstract

Jeltes, R., Burghardt, E., and Breman, J. (1971). Brit. J. industr. Med., 28, 96-99. Gas chromatographic determination of phosgene and dichloroacetylene in air. Phosgene and dichloroacetylene vapours may be present in the working environment near places where chlorinated hydrocarbons are used, including exposure chambers and the like in which people or animals are deliberately exposed to chlorinated hydrocarbons to investigate the effects of these substances. A gas liquid chromatographic method was developed for the determination of sub-Threshold Limit Value concentrations of phosgene and dichloroacetylene. Using electron capture detection, concentrations from 0·02 ppm of each compound could be determined.
