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╳10-3～1.0╳10-3g，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.2╳10-3～1.0╳10-3mg/m3。
浩瀚色谱(山东)应用技术开发有限公司采用"吸附管采样—热脱附—气相色谱-质谱法"同时测定环境空气中甲硫醇、乙硫醇、甲硫醚、乙硫醚和二甲基二硫醚5种有机硫化物,以全扫描模式定性,选择离子扫描法定量。考察了吸附管类型、采样流量、样品保存方式等因素对样品回收率的影响。

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. uses "adsorption tube sampling thermal desorption gas chromatography-mass spectrometry" to simultaneously determine five organic sulfides, including methyl mercaptan, ethyl mercaptan, methyl sulfide, ethyl sulfide, and dimethyl disulfide, in ambient air. The full scan mode is used for characterization, and ion scanning method is selected for quantification. The influence of factors such as adsorption tube type, sampling flow rate, and sample preservation method on sample recovery rate was investigated.
