A simple electron impact ionization source interface was developed for a combined capillary column supercritical fluid chromatography and mass spectrometry systems (SFC-MS). The sensitivity of the system was illustrated by the analysis of a sample containing 100 pg quantities of 4-aminobiphenyl, benzidine, and 3,3'-dichlorobenzidine. An analysis was also performed of the labile pesticide aldicarb. The latter analysis was performed additionally to determine the thermal effects of the chromatography. The total system was shown to enhance the flexibility of SFC-MS compared to standard liquid chromatography-mass spectrometry.
