A computer program to selectively locate the mass spectra of chlorinated compounds in a gas chromatography-mass spectrometry data set is described. The method is based on a search for chlorine isotope patterns and functions as a chlorine-selective "detector". Its performance has been evaluated using

โฆ Synopsis
A chlorine-selective chromatographic detector based on the computer analysis of gas chromatographic-mass spectrometric data was described in the previous paper. The presence of chlorine is inferred from isotope cluster patterns in the mass spectra; the computer is instructed to locate these patterns and indicate which spectra are most likely to arise from chlorinated compounds. The application of this detector to a drug metabolism study and the analysis of chlorinated species in an environmental matrix are presented. The performance of the detector in these systems is quite good, even for compounds of low abundance in a mixture.
