多潘立酮片含量测定的不确定度分析

Measurement uncertainty in determination of domperidone tablets

目的对紫外分光光度法测定多潘立酮片含量的测量不确定度进行评定分析,以期找到影响不确定度的因素。方法按照测量步骤,根据《测量不确定度评定与表示》、《化学分析中不确定度的评估指南》中有关规定评估其不确定度。结果量化各不确定度分量,提出了该法的合成不确定度评估结果。结论计算出扩展不确定度U=2.4%(k=2)。

Aim To analyze the measurement uncertainty in determination of domperidone tablets with UV,and meanwhile to find out the relative factors. Methods In accordance with measurement steps, based on＂ Evaluation and Expression of Uncertainty in Measurement＂,＂ Chemical Analysis of Uncertainty in Evaluation Guide＂ their uncertainty was assessed. Results The expanded measurement un- certainties were quantified,and the evaluation results of measurement uncertainty were drawn. Conclusion Expanded uncertainty U was 2.4% （k =2）.
