摘　　要：采用高效液相色谱-串联质谱法对食品接触材料中2,4-二氨基甲苯进行测定,同时对其不确定度进行评定。实验结果表明,标准工作曲线拟合对不确定度的影响最大,测量重复性的影响次之,它们是不确定度的主要来源。The determination of 2,4-TDA in food contacting materials was established by high performance liquid chromatography-tandem mass spectrometry(HPLC-MS/MS)method.And the uncertainty was evaluated.The result shows that working curve and repeatability of measurement were the main source of uncertainty.

关 键 词：高效液相色谱-串联质谱法 2 4-二氨基甲苯 不确定度
