BS EN 16858:2017规定了食品中三聚氰胺和三聚氰酸的测定方法 液相色谱法与串联质谱法相结合的食品。方法 已在实验室间研究中通过分析以牛奶为基础的婴儿配方奶粉的加标样品进行验证 配方奶粉、大豆基婴儿配方奶粉、奶粉、全脂牛奶、大豆饮料和牛奶巧克力 三聚氰胺为0.71 mg/kg至1.43 mg/kg，三聚氰酸为0.57 mg/kg至1.45 mg/kg。限制 食品中三聚氰胺和三聚氰酸的定量（LOQ）分别为0.05 mg/kg和0.25 mg/kg， 分别地三聚氰胺的工作范围上限为10 mg/kg，最高为25 mg/kg 三聚氰酸。交叉引用:EN ISO 3696:1995 ISO/IEC 5725-2:1994购买本文件时可获得的所有现行修改件均包含在购买本文件中。

BS EN 16858:2017 specifies a method for the determination of melamine and cyanuric acid in foodstuffs with liquid chromatography in combination with tandem mass spectrometry. The method has been validated in an interlaboratory study via the analysis of spiked samples of milk based infant formula, soy based infant formula, milk powder, whole milk, soy drink and milk chocolate ranging from 0,71 mg/kg to 1,43 mg/kg for melamine and 0,57 mg/kg to 1,45 mg/kg for cyanuric acid. The limits of quantification (LOQ) for melamine and cyanuric acid in food are 0,05 mg/kg and 0,25 mg/kg, respectively. The upper limit of the working range is up to 10 mg/kg for melamine and up to 25 mg/kg for cyanuric acid.Cross References:EN ISO 3696:1995 ISO/IEC 5725-2:1994All current amendments available at time of purchase are included with the purchase of this document.
