Abstract
AbstractTwo glass capillary gas chromatographic systems were equipped with inert effluent splitters which allowed simultaneous data acquisition using nonspecific and element‐specific detectors. Simultaneous detection was achieved using the nonspecific flame ionization detector (FID) and the Hall® electrolytic conductivity detector (HECD) operated in either the sulfur‐or the nitrogen‐specific mode. Typical application of the simultaneous detection system as applied to analysis of petroleum residues is briefly described. The Hall electrolytic conductivity detector can be made element specific for halogen‐, sulfur‐, or nitrogen‐containing compounds. Simultaneous detection enhances the information yield from a single sample injection and proves to be a powerful complementary technique when used with computerized gas chromatography/mass spectrometry.
