| 摘 要： | 文章系统分析了热解吸直接进样气相色谱法检测室内空气中苯浓度的不确定度来源，对各不确定度分量进行了量化，提出该方法的合成不确定度。通过对各不确定度分量的分析得到，室内空气中苯浓度检测主要来源于苯标准气体浓度、苯标准曲线的拟合和整个实验的重复性，计时误差、温度和气压引入的不确定度基本可以忽略。

| Abstract: | The uncertainty of determination for benzene in indoor air was analyzed in the paper. Through the uncertainty analysis, the following conclusion could be made:(1) The uncertainty of this method mainly came from the precision of correct mixture of benzene, regression for standard curve and the repeatability of the entire experiment.(2) The uncertainty of timing error, temperature and pressure could be ignored. |
