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 × 10-9-1.0 × 10g. When the concentration of the four components in the gas sample is higher than 1.0mg/m3, 1-2mL of the 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 0.2 × 10-3 to 1.0 × 10-3mg/m3, respectively
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses gas sampling bags to analyze four types of odorous sulfides in the air, including hydrogen sulfide, methyl mercaptan, methyl sulfide, and dimethyl disulfide, after the samples are processed by a three-stage cold trap pre concentrator using gas chromatography. The experiment shows that this method has good linearity, with a detection limit of 3.1 × 10-5 mg/m3~1.2 × 10-4mg/m3, precision of 0.8%~1.3%, and blank spiked recovery rate of 84.6%~112.0%. This method is accurate, reliable, and suitable for determining sulfides.
