Sulfur chemiluminescence detection

Nitrogen compounds in middle distillates can be detected selectively by chemiluminescence. Individual nitrogen compounds can be detected down to 100 ppb nitrogen. Gas chromatography with either sulfur chemiluminescence detection or atomic emission detection has been used for sulfur-selective detection.

A simple oxidative combustion does not generate a sulfur chemiluminescent species since SO2 does not chemiluminesce with ozone. Sulfur chemiluminescence detection has the advantage that SO is produced during FID operation. When SO reacts with ozone, a strong blue chemiluminescence signal is emitted by the resulting SOj. The signal is isolated from other radiations and detected by a photomultiplier tube.

Sulfur Chemiluminescence Detection—As sulfur compounds elute fiom the gas chromatographic column they are combusted in a flame ionization detector (FID). These combustion products are collected and transfer to a Ifur chemiluminescence detector (SCD). This detection technique provides a highly senative, selective, and linear response to volatile sulfur compounds and may be used simultaneously while the usual fixed gas and hydrocarbon determinations are being made.
