ABSTRACT
The technique of scanning a preselected set of ions employing a combined gas chromatography mass spectrometer computer system has been investigated to ascertain the advantages and disadvantages of such a procedure. This technique allows one to determine gas chromatographic retention data with with a high degree of precision and accuracy, in rapid temperature programming operation, due to shortening of the mas spectral scanning interval. Signal-to-noise ratio in ion abundance recordings can be enhanced by increasing the dwell time for as many as 100 ions without lenghtening the scanning interval. The utility of such an approach was demonstrated by analysis of complex mixtures isolated form human urine and cerebrospinal fluid.
