| 摘 要： | 采用气质联用法对电器塑料产品中的多环芳烃进行了分析,通过建立数学模型,分析了测量不确定度的主要来源有样品质量、样品萃取液体积、样品萃取液测定浓度、试剂空白液测定浓度以及平均回收率。对各不确定度分量进行了评定,当多环芳烃含量为239.03mg/kg时,合成不确定为7.41mg/kg,扩展不确定度为14.82mg/kg。

| Abstract: | The PAHs in electronic plastic products was detected by GC-MS,and the method for the uncertainty estimate was obtained.Through the maths model,the uncertainty components were evaluated,which included the mass of the sample,the extraction volume of the sample,the concentration of the sample extraction and the blank extraction,recyle.According to this method,the uncertainty of the compinents of uncertainty were analyzed,quantified and composed.The expanded uncertainty of PAHs was 14.82 mg/kg. |
