本方法适用于恶臭污染源排气和环境空气中硫化氢、甲硫醇、甲硫醚和二甲二硫的同时测定。气相色谱仪的火焰光度检测器（GC-FPD）对四种成分的检出限为0.2×10-9～1.0×10<上上标-9>g，当气体样品中四种成分浓度高于1.0mg/m3时，可取1～2mL气体样品直接注入气相色谱仪分析。对1L气体样品进行浓缩，四种成分的方法检出限分别为0.2×10-3～1.0×10-3mg/m3
浩瀚色谱（山东）应用技术开发有限公司,使用气体采样袋，样品经三级冷阱预浓缩仪处理后，气相色谱分析空气中硫化氢、甲硫醇、甲硫醚、二甲二硫共4种恶臭硫化物。实验表明，此方法线性好，检出限为3.1×10-5 mg/m3 ~1.2×10-4mg/m3，精密度为0.8%~1.3%，空白加标回收率为84.6%~112.0%。这种方法可以准确可靠且适用于测定硫化物。

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.
