摘要
目的分析UV法测定维生素B12注射液含量的测量不确定度。方法建立UV法测定含量的数学模型,分析测量不确定度的来源并对各分量进行量化分析和评估,合成标准测量不确定度,给出扩展测量不确定度报告。结果 UV法测定维生素B12注射液含量的扩展测量不确定度为1.0%,测量结果表示为(98.4±1.0)%,k=2。结论分析产生不确定度的主要来源,为有效地控制该含量测定方法的准确性提供可靠的理论依据。
Objective To evaluate the measurement uncertainty for the content determination of Vitamin B12 injection by UV. Methods The model of content determination by UV was established. The uncertainty sources had been analyzed. Each active component of uncertainty was calculated,and the extended uncertainty was obtained. Results The extended uncertainty for the UV determination of Vitamin B12 was 1.0%,the result of content determination was（98. 4±1. 0）%,k=2. Conclusion The main sources of uncertainty were analyzed,which provided a reliable theoretical basis for effectively controlling of this method.
