生鲜乳中黄曲霉毒素M1的不确定度测定

Uncertainty evaluation for determination of aflatoxin M1 in fresh milk

采用同位素稀释液相色谱-串联质谱法测量生鲜乳中黄曲霉毒素M1,建立了结果不确定度的数学模型。根据《测量不确定度的评定与表示》相关规定对测定过程中的不确定度来源和各分量进行分析计算与结果的表示。

The isotope diluent liquid chromatography - tandem mass spectrometry measured the aflatoxin M1 in fresh milk, and establishes the mathematical model of uncertainty evaluation.According to the Evaluation and Expression of Uncertainty in Measurement of the uncertainty in the process of sources and analyzed the results of calculation and the components in the said.
