摘要: 依据JJG1059-1999《测量不确定度评定与表示》,采用分层建模的方法,建立了气相色谱法测定河蟹中多氯联苯的不确定度评定的数学模型,通过研究整个测定过程,系统分析该测定方法检测结果不确定度的来源,并对不确定度各个分量进行评估和合成,得出了气相色谱法测定河蟹中多氯联苯残留量不确定度的主要影响因素的结论。

Abstract: According to JJG1059-1999 Measurement Uncertainty and Results Indication, a mathematic model of uncertainty evaluation for the determination of polychorinated biphenyls (PCBs) in river crab by gas chromatography (GC) was established. The whole determination procedure was systematically investigated to analyze the sources of determination uncertainty. Meanwhile, the uncertainty of each variable was also evaluated and synthesized. The major affecting factors of GC determination uncertainty for PCBs in river crab were achieved.

Key words: gas chromatography (GC), river crab, polychorinated biphenyls (PCBs), uncertainty
