中文摘要: 参考GB/T 23296.16-2009《食品接触材料高分子材料食品模拟物中2，2-二（4-羟基苯基）丙烷（双酚A）的测定高效液相色谱法》测定食品接触材料（金属空罐）的双酚A迁移量。通过分析测定过程中的各种不确定度来源，计算各不确定度分量，得出金属空罐的双酚A迁移量为0.005 53 mg/dm2，扩展不确定度为0.000 38 mg/dm2。比较各不确定度分量大小可知，高效液相色谱法测定食品接触金属空罐双酚A迁移量的不确定度主要来自双酚A标品的纯度和标准曲线的拟合。
Abstract:To base on GB/T 23296.16-2009，the bisphenol A migration in food contacted materials（metal cans）was determined.By analyzing and calculating the various sources of uncertainty during the entire determination process，the amount of the bisphenol A migration in metal cans was 0.005 53 mg/dm2with expanded uncertainty of 0.000 38 mg/dm2.Comparison the amount of each uncertainty，the uncertainty of the bisphenol A migration in food contacted materials（metal cans）determined by HPLC mainly came from the purity of bisphenol A and the fitting of standard curve.
keywords: HPLC food contacted materials bisphenol A uncertainty
