摘　　要：建立液相色谱串联四极杆质谱法测定奶粉中黄曲霉毒素M1结果不确定度评定的数学模型,依据《测量不确定度的评定与表示》相关规定对测定过程的不确定度来源和各分量进行分析和计算,结果表明,当奶粉中的黄曲霉毒素M1残留量为0.147μg/kg时,其扩展不确定度为0.012μg/kg.The mathematical model was established to evaluate the uncertainty in measuring the residual quantity of aflatoxin M1 in milk powder by HPLC-MS/MS in this paper. The source of uncertainty and all the components were analyzed and calculated according to ＂Evaluation and Expression of Uncertainty in Measurement＂. The results showed that the expanded uncertainty was 0.012 ug/kg when the content of aflatoxin M1 was 0.147ug/kg.
