摘　　要：以JJF 1059.1-2012《测量不确定度评定与表示》为依据,对高效液相色谱法测定食品接触材料食品模拟物中三聚氰胺含量进行不确定度评定,结果显示四种食品模拟物中三聚氰胺含量分别为0.502±0.023mg/L(水)、0.298±0.023mg/L(10%乙醇)、7.027±0.34mg/L(3%乙酸)和0.637±0.046 mg/kg(玉米油),其相对标准不确定度均小于10%。According to JJF1059.1-2012“Evaluation and Expression of Uncertainty in Measurement”,the uncertainty of melamine content in food simulants of food contacted materials determined by HPLC was evaluated.The results showed that the melamine content in food simulants water,10%ethanol,3%acetic acid and corn oil were(0.502±0.023)mg/L,(0.298±0.023)mg/L,(7.027±0.34)mg/L and(0.637±0.046)mg/kg,respectively,And the relative standard uncertainty were below10%.
