摘　　要：为了建立统一定量测定粗苯中三苯含量的方法,采用带火焰电离检测器的气相色谱仪,在典型条件下进行粗苯不同样品的实验,研究了面积百分比法和采用美国有效碳数因子法、文献校正因子归一化法、实测校正因子法测定的粗苯中三苯含量结果的差异,分析了不同分析方法对实验结果的影响,确定了面积百分比法的合理性,并对20个样品的分析结果误差进行了验证。To set up a unified quantitative method for determining the contents of benzene, toluene and xylene in crude benzene, the gas chromatograph （GC） with flame ionization detector （FID） was adopted to make tests of different samples of crude benzene under typical conditions. The differences in the contents of benzene, toluene and xylene in crude benzene as determined respectively by the area ratio method, the American carbon number factor method, the literature correction factor normalized method and the measured correction factor method were studied. The impact of different test methods on the test result was analyzed, and it was determined that the area ratio method was most rational. The errors of the analysis results of 20 samples were verified.
