对高效液相色谱一串联质谱法测定猪肉中磺胺多辛含量过程中引入的不确定度进行了分析和评定,通过试验计算出猪肉中磺胺多辛含量测量结果的不确定度。在置信水平为95%,包含因子k=2时,其相对扩展不确定度8.58%;当磺胺多辛含量为35.37μg/kg,其扩展不确定度为3.03μg/kg。样品的前处理所引入的不确定度对合成不确定度的贡献最大。

Uncertainties from the test results of sulfadoxine in pork by liquid chromatography tandem mass spectrometry were analyzed and assessed. The relative expended uncertainty calculated from the experimental date was 8.58% ,when the designed incredible probability was 95%(k=2). The expended uncertainty was 3.03 g / kg,while the content of sulfadoxine in the sample was 35.37 g / kg. The contribution of the uncertainty introduced by the sample pretreatment was the largest part to the combined uncertainty.
