ANALYSIS OF SULFUR-COMPOUNDS BY CAPILLARY COLUMN GAS-CHROMATOGRAPHY WITH SULFUR CHEMI-LUMINESCENCE DETECTION

A new gas chromatographic detector for the determination of sulfur-containing compounds has recently become commercially available. The sulfur chemiluminescence detector (SCD) is based on forming sulfur monoxide in a reducing flame from sulfur-containing compounds being eluted from a gas chromatograph. The sulfur monoxide that is formed is subsequently detected by its chemiluminescent reaction with ozone. This new detector has been found to be at least one order of magnitude more sensitive than most flame photometric detectors. It produces a linear response, possesses a sulfur-to-carbon selectivity greater than 106, does not suffer appreciably from quenching, and has a response to various sulfur species that is nearly equimolar.; A new gas chromatographic detector for the determination of sulfur-containing compounds has recently become commercially available.
