NEW SULFUR-SELECTIVE DETECTORS FOR GAS AND LIQUID CHROMATOG RAPHY BASED ON REACTIONS WITH FLUORINE

THE DEVELOPMENT OF NEW SELECTIVE DETECTORS FOR GAS AND LIQUID CHROMTOGRAPHY FOR THE SENSITIVE MEASUREMENT OF SULFUR-CONTAINING COMPOUNDS IS PROPOSED. THESE DETECTORS ARE BASEDON FLUORINE-INDUCED CHEMILUMINESCENCE AND ARE HIGHLY SE SELECTIVE FOR SULFIDES, DISULFIDES AND MERCAPTANS. THE MAJORRESEARCH PROPOSED IS THE DEVELOPMENT OF NEW SOURCES OF FLU FLUORINE WHICH WILL BE SAFE, PROTABLE, AND LOW IN COST. INITIAL STUDIES WILL BE FOCUSED ONT HE SELECTIVE ANALYSIS OFMETHYL MERCAPTAN AND DIMETHYL SULFIDE. THE POTENTIAL FOR USING THESE SAME SENSORS FOR MONITORING OTHER ATMOSPHERIC SULFUR COMPOUNDS, INCLUDING SULFUR DIOXIDE, CARBONYL SULFIDE, CARBON DISULFIDE, HYDROGEN SULFIDE, DIMETHYL SULFOXIDE ANDDIMETHYL DISULFIDE WILL ALSO BE EXPOLORED.
