This method is applicable for the simultaneous determination of hydrogen sulfide, methyl mercaptan, methyl sulfide, and dimethyl disulfide in the exhaust gas 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 0.2-10-3 to 1.0-10-3g. When the concentration of the four components in the gas sample is higher than 1.0mg/m3, 1-2mL of gas sample can be directly injected into the gas chromatograph for analysis. Concentrate a 1L gas sample, and the detection limits for the four components are. 2 ╳ 10-3 to 1.0 ╳ 10-3mg/m3, respectively.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. used cold trap pre concentration gas chromatography/mass spectrometry to determine six sulfides including hydrogen sulfide, methyl mercaptan, methyl sulfide, carbon disulfide, dimethyl disulfide, and thiophene in ambient air, and discussed the influence of sampling container materials. The method has good linearity, with detection limits of 1.3 μ g/m3 to 5.2 μ g/m3 for 6 sulfides, and RSD ≤ 8.6% for parallel determination of mixed standard gas
