“…Quantitative determination of the sulfur-containing compounds in gases and liquid samples is vitally important for environmental monitoring, , food quality and safety control, , quality inspection of petro , and natural gas, and chemical warfare agent inspection. , Sulfur selective detectors employed in a gas chromatograph (GC) include flame photometric detector (FPD) − with a limit of detection (LOD) of 1–10 pg S s –1 , pulsed flame photometric detector (PFPD) , with LOD of 0.1–1 pg S s –1 , sulfur chemiluminescence detector (SCD) , with LOD of ∼0.1 pg S s –1 , atomic emission detector (AED) with LOD of ∼1 pg S s –1 , and electron capture detector (ECD) , for the detection of hydrogen sulfide. Among these sulfur detectors, FPD is the most popular one because of its reasonable sensitivity, easy operation, robustness, and low cost…”
