- Scope
- This method is suitable for the simultaneous determination of hydrogen sulfide, methyl mercaptan, methyl sulfide and dimethyl disulfide in the exhaust of odor pollution sources and ambient air. The detection limit of the flame photometric detector (GC-FPD) of the gas chromatograph for the four components is 0.2×10-9～1.0×10-9g, when the four components in the gas sample When the component concentration is higher than 1.0mg/m3, 1-2mL gas sample can be directly injected into the gas chromatograph for analysis. Concentrating 1L gas sample, the detection limits of the four components were 0.2×10-3～1.0×10-3mg/m3, respectively.
