Sulfur selective detector is a kind of instrument which is used to determine sulfur content in hydrocarbon processing industry. It mainly has four types: Sulfur Chemiluminescence Detector (SCD), Flame Photometric Detector (FPD), Pulsed Flame Photometric Detector (PFPD) and Atomic Emission Detection (AED). Sulfur Chemiluminescence Detector (SCD) uses sulfur compounds to react with ozone to form excited SO2, which emits characteristic blue spectra, to judges the composition of matter, Flame Photometric Detector (FPD) judges the composition of matter by using spectra of characteristic wavelength emitted by sulfur and phosphorus when phosphorus or sulfur organic compounds are burned in hydrogen-rich flame, Atomic Emission Detection (AED) uses the characteristic emission spectra of atoms or ions of each element to judge the composition of matter, On the basis of FPD, Pulsed Flame Photometric Detector (PFPD) use pulse flame instead of the traditional continuous flame.

Global sulfur selective detector market was valued at 377 Million US$ in 2018 and is projected to reach 516 Million US$ by 2024, at a CAGR of 5.39% during the forecast period. The key consumption markets locate at developed countries. The Asia-Pacific take a market share of 45%, followed by Europe with 22%, North America has a 17% market share.
