金芩芍注射液含量测定的不确定度分析

Evaluate the Uncertainty of Content Determination of Jinqinshao Injection

为了探讨金芩芍注射液含量测定的不确定度分析评定,通过分析测量过程,建立数学模型,确定不确定度来源,评价各标准不确定度分量合成标准不确定度,评定扩展不确定度,给出不确定度评定结果报告。金芩芍注射液含量测定结果可表示为(2.96±0.04)mg/m L(k=2)。测量结果不确定度的主要来源为天平称量、高效液相色谱仪和小体积玻璃量具。

Evaluate the uncertainty of content fetermination of Jinqinshao Injection. The effects on measuring are discussed, a mathematical model of uncertainty of Jinqinshao Injection was established, the uncertainty of each variable was calculated, at last calculated the expanded uncertainty and showed the report of uncertainty of determination. The result of content determination can be expressed as （2.96±0.04） mg/mL （k = 2）. The main sources of measurement uncertainty were balance range, high performance liquid chromatography and small capacity measuring vessel.
