摘要：

Concentrations of chloroform, carbon tetrachloride, trichloroethylene, and tetrachloroethylene, ranging from 0.1 ppb to low ppm, are conveniently determined at ambient temperature using headspace gas chromatography in conjunction with electron capture detection. Effects of the analysis conditions, sample matrix, and sample history are evaluated in detail. The headspace method, which is compared with the purge-trap procedure, is shown to be accurate and exhibit a standard deviation of about 5 % for routine analyses of drinking, natural, and industrial waters. © 1979, American Chemical Society.
