Abstract

Low temperature gas chromatography (LT-GC) coupled on-line with inductively coupled plasma mass spectrometry (ICP-MS) has been used to identify volatile metal and metalloid compounds in human breath. After cryogenic sampling, the gas sample: has been separated without any clean-up by increasing the temperature (-100 to +200 degrees C). Simultaneous determination of 11 elements with ICP-MS was used for screening analysis. The detection limits of volatile compounds ir. intra-oral air are in the range of ng m(-3). Dimethyl selenium has been determined in each gas sample from six test persons in the range of 0.08 to 0.98 mu g m(-3).
