| 摘 要： | 本文利用气相色谱法对胶粘剂中苯进行了测定,当苯含量为0.32%时,扩展不确定度U=0.01%,(K=2)。同时从标准溶液配制、稀释过程、标准工作曲线拟合、样品称量、样品定容、峰面积测量以及方法重复性等几个方面对测量不确定度来源进行了分析和量化评定,指出主要的不确定度来源是方法的重复性、标准工作曲线拟合以及峰面积的测量。

| Abstract: | The uncertainty for the determination of benzene in adhesives by gas chromatography was analyzed.The test indicated that when: the benzene content was 0.32%,the expended uncertainty was 0.01%.The sources of the uncertainty were anglyed and determined which resulted from preparation of standard solution,dilution process,linear fitting,weight of the sample,peak area,volume of dissolved and method precision.Through evaluation it was indicated that the main uncertainty for the determination were method precisio... |
