GB/T 14678-1993 Air Quality - Determination of Hydrogen Sulfide, Methylthiol, Methyl Sulfide and Dimethyl Disulfide - Gas Chromatography Method

GB/T 14678-1993 Air Quality - Determination of Hydrogen Sulfide, Methylthiol, Methyl Sulfide, and Dimethyl Disulfide - Gas Chromatography - Detailed Information:

This method is applicable 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 four components is 0.2 × 10-1.0 × When the concentration of the four components in the gas sample exceeds 1.0mg/m, 1-2mL of the gas sample can be directly injected into the gas chromatograph for analysis. Concentrate 1L gas sample with detection limits of 0.2 for each of the four components × 10-1.0 × 10mg/m.
