目的:建立紫外-可见分光光度法测定盐酸雷尼替丁胶囊含量的不确定度评定方法;方法:根据测量过程,全面鉴别不确定度来源,计算各分量的不确定度,建立数学模型,最后计算出合成标准不确定度uc和扩展不确定度U95.结果:盐酸雷尼替丁胶囊含量测定的结果可表示为98.6%±1.0%(k=2),合成标准不确定度uc为0.5%和扩展不确定度U95为1.0%;结论:本方法适用于紫外-可见分光光度法含量测定的不确定度评定,对合理地赋予被测定结果的分散性具有重要意义。
OBJECTIVE: To establish a UV-Vis spectrophotometric method for the determination of the uncertainty of Ranitidine Hydrochloride Capsules. Methods: According to the measurement process, the sources of uncertainty were fully identified, the uncertainty of each component was calculated, and the mathematical model was established. Finally, The calculated standard uncertainty uc and extended uncertainty U95 were calculated.Results: The results of determination of ranitidine hydrochloride capsule can be expressed as 98.6% ± 1.0% (k = 2), the synthetic standard uncertainty uc is 0.5% And the extended uncertainty U95 is 1.0%. Conclusion: The method is suitable for the evaluation of the uncertainty of UV-visible spectrophotometric determination of content, which is of great significance to the decentralization of the measured results.
