haohan环境空气硫化氢等10种含硫化合物的测定HH-1毛细管柱应用安捷伦柱长 60 m，内径 0.25 mm，膜厚 1.0 μm

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，采用大气预浓缩仪-GC-FPD建立了环境空气中10种含硫化合物的测定方法.结果表明,大气预浓缩仪-GC-FPD的系统背景值低,仪器的灵敏度高,系统对硫化物无残留;方法的检出限在0.0072～0.248ng范围内,比国标方法的检出限低一个数量级以上;方法的精密度较高,除硫化氢外,10种化合物的精密度都在6.8％以内,硫化氢的精密度在22％以内,满足挥发性有机物测定的要求;对质控样品的测定结果表明,方法的准确度在96％～107％之间,准确度高.上述结果表明,该方法可用于环境空气中痕量含硫化合物的检测。

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. has established a method for the determination of 10 sulfur-containing compounds in ambient air using an atmospheric pre concentrator GC-FPD The results indicate that the background value of the atmospheric pre concentrator GC-FPD system is low, the sensitivity of the instrument is high, and there is no residual sulfide in the system; The detection limit of the method is within the range of 0.0072-0.248ng, which is more than one order of magnitude lower than the detection limit of the national standard method; The precision of the method is relatively high. Except for hydrogen sulfide, the precision of 10 compounds is within 6.8%, and the precision of hydrogen sulfide is within 22%, meeting the requirements for volatile organic compound determination; The measurement results of the quality control samples show that the accuracy of the method is between 96% and 107%, indicating high accuracy The above results indicate that this method can be used for the detection of trace sulfur-containing compounds in ambient air.
