摘要
建立固体吸附/热脱附-气相色谱法测定环境空气中苯系物的不确定度评定方法,分析测定过程中不确定度的来源,进行各不确定度分量的评估,并给出合成相对标准不确定度和扩展不确定度。
This paper established a method for evaluating uncertainty of BTEXs measurement in Ambient Air by Solid adsorption thermal desorption-Gas Chromatography. The sources of uncertainty and main influential factors of uncertainty in the measurement process were analyzed and synthesized according to Evaluation and Expression of Uncertainty in Measurement（JJF 1059 1999） ,and the final expanded uncertainty was given.
