测定丁硫克百威含量的不确定度分析

采用高效液相色谱法测定丁硫克百威含量，并求出了不确定度值。按照分析丁硫克百威含量的企业标准，用外标法进行测定，建立了相应的数学模型，确定了分析过程中引起不确定度的各个分量。并予以计算得出结论：分析丁硫克百威含量的不确定度主要由3个部分组成，即标准品与样品溶液的配制；丁硫克百威标准品的纯度；标准品溶液及样品溶液中丁硫克百威的峰面积。

Analyse Uncertainty in Measurement of Carbosulfan Content

Carbosulfan content was measured by HPLC,and the value of uncertainty was calculated.A mathematical model was built up and the various factors were determined by applying external standard method.It was concluded that the uncertainty consists of three parts: preparation of the standard solution and the sample solution,purity of carbosulfan standard,chromatographic peak area of carbosulfan in the standard solution and the sample.
