摘　　要：采用4柱联用-双检测器-多通道切换气相色谱仪定性、定量分析苯乙烯尾气中的各组分，结果表明，准确度和精密度均较高，平行测定6次，11种组分的相对标准偏差范围为0.04％～18％。Using 4 column combined with double detector and multi-channel switching ,the method for qualitative and quantitative determination of styrene in the tail gas by multidmensional gas chromatography was established. The results show the method has high accuracy and precision .The relative standard devi-ation is in the range of 0.04%-18%.
