In the past, headspace analysis has been employed, almost exclusively, in combination with gas chromatography. In this paper the on-line dynamic headspace analysis of liquid streams with direct mass spectrometry detection is described. The limits of detection for acetone and methyl iodide are 1 and 2 mu g ml(-1), respectively. The relative standard deviations (n = 6) for the determination of a 100 mu g ml(-1) concentration stream are 3.0 and 5.3% for acetone and methyl iodide, respectively.
