Unmodified standard gas chromatographs are reported to be useful for the determination of a large number of ambient hydrocarbons. Packing of standard injector glass liners with an adsorbent permits thermal desorption in the injector on to the chromatographic column. Coupling to a personal sampling pump permits exposure-related sampling. The potential of the technique is illustrated by applications with the Tenax GC adsorbent. Precautions required to avoid artifacts when working in the subnanogram range are described.

Nyckelord: air pollutants, gas chromatography, alkanes, benzene, alkylbenzenes


The method described was used during a period of about ten years in a wide range of applied environmental studies relating to hydrocarbons from traffic and industry.
