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.
