Since sulfur compounds can work as catalyst poisons, they are measured in chemical processes. Shown below is an example of the analysis of sulfur compounds in natural gases. PFPD was used as the detector.

System GC

Conventional gas chromatographs require skilled operatorsto ensure precise analysis. By utilizing valve actuation to switch flow lines, system GCs provide key advantages over conventional systems for operators, such as automatic sampling, more precise analysis, and analytical time savings.
