Summary A modified GC sampling system and its analytical use are described for the determination of volatile components of human breath or in ambient atmosphere with flame-ionization detection (FID). The difficulties of collection for low concentration samples were alleviated by using a very small trapping column packed with activated charcoal. The collected samples can be measured directly after thermal desorption onto the chromatographic column (packed with Porapak Q). The preconcentration recoveries for pentane, methanol, ethanol and acetone have been studied.
