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PE580  详细信息：

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mi、二硫化碳、甲乙liu醚、噻吩、乙硫mi和二甲er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集空气样品，在预浓缩系统中经3级冷阱捕集后，用气相色谱-FPD技术测定环境空气中10种痕量有机硫化物。对试验条件进行优HUA，使得甲硫醇、乙硫醇、甲硫MI、二硫化碳、噻吩、乙硫MI和二甲ER硫MI等10种有机硫化物在21．57μg/m3～338．48μg/m3范围内线性良好。试验表明，10种有机硫化物的方法检出限为0．0045μg/m3～0．039μg/m3；标ZHUN气体平行测定6次结果的 RSD为2．9％～6．9％，加标回收率为92．8％～97．9％。用该方法测定实际空气样品，结果满意。

Determination of 10 sulfur-containing compounds including hydrogen sulfide in ambient air using HH-1 capillary column with PE580

Determination of 10 sulfur-containing compounds including hydrogen sulfide in ambient air using HH-1 capillary column with PE580 detailed information:

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 ether, thiophene, ethyl sulfide, and dimethyl sulfide, 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 a tank to collect air samples. After being captured in a three-stage cold trap in a pre concentration system, 10 trace organic sulfides in ambient air are determined using gas chromatography-FPD technology. Optimize the experimental conditions to achieve good linearity of 10 organic sulfides, including methyl mercaptan, ethyl mercaptan, methyl sulfide MI, carbon disulfide, thiophene, ethyl sulfide MI, and dimethyl ER sulfide MI, within the range of 21.57 μ g/m3 to 338.48 μ g/m3. The experiment shows that the detection limit of 10 organic sulfide methods is 0.0045 μ g/m3 to 0.039 μ g/m3; The RSD of six parallel determinations of ZHUN gas ranged from 2.9% to 6.9%, and the recovery rate of spiked samples was 92.8% to 97.9%. The method was used to measure actual air samples with satisfactory results.
