高效液相色谱法测定三聚氰胺的不确定度评定

The Evaluation of Uncertainty of Measurement of Melamine by High Performance Liquid Chromatography

分析了高效液相色谱法测定饲料中三聚氰胺的不确定度来源,并对各不确定度分量进行了评定,得出了三聚氰胺检测结果的相对合成标准不确定度。结果表明检测过程的精密度、检测程序的偏差及校准曲线对检测结果的不确定度影响最大。

Analyse the sources of uncertainty of measurement of melamine in the feed by high performance liquid chromatography（HPLC）,and evaluate each component of uncertainty.Related combined standard uncertainty of melamine is achieved.The result demonstrates that the components most infecting the uncertainty are precision,deviation of testing procedure and calibration curve.
