Abstract
The basis of operation of a capillary gas chromatograph with a quadrupole mass spectrometer as a detector is reviewed. This is followed by the description of the optimization of a Finnigan MAT 5100 gas chromatograph-mass spectrometer-data system (GC/MS/DS) for the detection and identification of PCBs. In particular, the effects of increasing electron multiplier voltage and the use of multiple ion detection (MID) scan sequences on the sensitivity of the quadrupole mass spectrometer are investigated. Both increasing the electron multiplier voltage and the use of specialized MID scan sequences were found to result in an improved detector response.
