本标准规定了测定环境空气和无组织排放监控点空气中硫化氢等10种含硫化合物的罐采样-预浓缩/气相色谱法。
本标准适用于环境空气和无组织排放监控点空气中硫化氢、羰基硫、甲硫醇、乙硫醇、甲硫醚、二硫化碳、甲乙硫醚、噻吩、乙硫醚和二甲二硫等10种含硫化合物的测定。当取样体积为400ml时，目标化合物的方法检出限为0.09μg/m3～0.3μg/m3，测定下限为0.36μg/m3～1.2μg/m3，详见附录A。
高浓度的其他种类挥发性有机物或其他含硫有机化合物影响目标化合物的测定时，可通过减少取样量、稀释样品或使用其他高选择性检测器进行分析。
浩瀚色谱（山东）应用技术开发有限公司，采用罐采样、三级冷阱预浓缩对气体样品进行前处理、GCFPD火焰光度检测器测定空气中硫化氢、甲硫醇、甲硫醚、二甲二硫、二硫化碳、羰基硫等10种硫化物。该方法灵敏度高、重复性好，该方法可用于空气中这些含硫类恶臭化合物的测定。采用该方法测定了污水处理厂周围空气中含硫恶臭类化合物的含量。

This standard specifies the tank sampling pre concentration/gas chromatography method for determining 10 sulfur-containing compounds, including hydrogen sulfide, in ambient air and unorganized emission monitoring point air.
This standard is applicable to the determination of 10 sulfur-containing compounds, including hydrogen sulfide, carbonyl sulfide, methyl mercaptan, ethyl mercaptan, methyl sulfide, carbon disulfide, methyl ethyl sulfide, thiophene, ethyl sulfide, and dimethyl disulfide, in ambient air and unorganized emission monitoring points. When the sampling volume is 400ml, the method detection limit of the target compound is 0.09 μ g/m3 to 0.3 μ g/m3, and the lower limit of determination is 0.36 μ g/m3 to 1.2 μ g/m3, as detailed in Appendix A.
When other types of volatile organic compounds or sulfur-containing organic compounds with high concentrations affect the determination of target compounds, analysis can be carried out by reducing the sample size, diluting the sample, or using other highly selective detectors.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses tank sampling, three-stage cold trap pre concentration for gas sample pretreatment, and GCFPD flame photometric detector to determine 10 types of sulfides in the air, including hydrogen sulfide, methyl mercaptan, methyl sulfide, dimethyl disulfide, carbon disulfide, carbonyl sulfide, etc. This method has high sensitivity and good repeatability, and can be used for the determination of these sulfur-containing odorous compounds in the air. This method was used to determine the content of sulfur-containing odorous compounds in the air around the sewage treatment plant.
