Abstract
The sulfur chemiluminescence detector was optimized for the analysis of organosulfur compounds by supercritical fluid chromatography. The flame gases used in this study were hydrogen and air. The highest sensitivity was found when a fuelβrich flame was used. The noise characteristics of the detector were determined. Flicker noise is the primary source of noise in this detector when analyte is present. The linear dynamic range of the detector under supercritical fluid chromatography conditions was typically three orders of magnitude. For the optimum flame gas conditions, the detection limits for twoβand threeβring organosulfur compounds were 10β1400 pg injected. The detection of sulfur in high molecularβweight polymers was also demonstrated.
