[目的]拟建立氯啶菌酯含量检测不确定度表达式,以明确实验各环节对检测结果的影响程度。[方法]通过对采用高效液相色谱法测定氯啶菌酯含量时各种不确定度分量的来源分析并加以评定。[结果]经计算合成不确定度及扩展不确定度,得出了氯啶菌酯测定的不确定度表达式。[结论]本实验结果适用于针对原药或制剂中氯啶菌酯含量检测过程中的不确定度进行评估。
[Objective] The research aimed to establish the expression of uncertainty of detection of chlorothalbroside in order to clarify the influence degree of each link on the test results. [Method] The sources of various uncertainty components in the determination of chlorothalonil content by HPLC were evaluated and evaluated. [Result] The uncertainty of the determination of chlorothalonil was obtained by calculating the synthetic uncertainty and the extended uncertainty. [Conclusion] The results of this experiment are suitable for assessing the uncertainty in the detection of TCB content in the original drug or preparation.
