Title: Chemiluminescence sulfur detection in capillary supercritical fluid chromatography

Abstract

The need for selective detectors in supercritical fluid chromatography (SFC) is particularly evident for the sensitive analysis of sulfur-containing species. These sulfur species are of interest to the environmental community, for the analysis of pesticides and atmospheric pollutants, as well as to the petroleum industry. Various detectors have been employed for the analysis of sulfur. The authors describe the use of a chemiluminescence sulfur detector (SCD) for the analysis of sulfur-containing organic analytes as separated by supercritical fluid chromatography. Detection limits of 35 and 115 pg of isopropylthiol and dodecanethiol, respectively, have been obtained for the SFC-SCD system with the linear dynamic range of about 10/sup 3/. Sulfur detectability appears to be independent of chromatographic pressure and the utility of the system is illustrated by the presentation of several real world analyses.
