摘　　要：建立了气袋采样-预浓缩进样-GC-MS同时测定污染源废气中8种有机硫化物的分析方法。方法线性良好,相关系数均大于0.998,检出限在0.002~0.004 mg/m3,RSD为0.8%~3.2%,加标回收率在94.0%~125%,完全满足定性定量分析要求。A method for simultaneous determination of 8 organosulfur compounds in exhaust gas by bag sampling-preconcentration injecting-GC-MS was developed.The performance index of the method was satisfied with the correlation coefficients greater than 0.998,the detection limits within the range of 0.002~0.004 mg/m3,relative standard deviation from 0.8%to 3.2%,and the recoveries from 94.0%to 125%,which fully met the qualitative and quantitative analysis requirements.
