摘要: 目的对调脂颗粒中姜黄素含量的测量不确定度进行评定分析。方法按测量不确定度原理及国家质量技术监督局发布的计量技术规范,建立高效液相色谱法(HPLC)测定调脂颗粒中姜黄素含量的测量不确定度并对其进行分析,分析诸多不确定因素对测量结果的影响,计算合成不确定度及扩展不确定度。结果测定调脂颗粒中姜黄素含量的扩展不确定度为每袋8.0mg,含量测定结果可表示为:每袋(97.7±8.0)mg(k=2)。结论本方法可用于测定调脂颗粒中姜黄素含量的测量不确定度分析。

Abstract: ObjectiveTo analyze the measurement uncertainty in determination of curcumin in Tiaozhi granules. MethodsAccording to the measurement uncertainty principle and National Measurement Technology Criterion, mathematic model of HPLC was established to analyze the effects of many uncertain factors on measurement results. Combined standard uncertainty and expanded standard uncertainty were calculated. ResultsThe expanded uncertainty was 8mg per bag and the results of determination could be expressed as(97.7±8.0)mg per bag(k=2). ConclusionThe established analytical method is applicable to the uncertainty analysis in the content determination of Tiaozhi granules.
