标准摘要
[中文适用范围]： 本文件规定了使用电感耦合等离子体质谱（ICP-MS）定量测定钙(Ca)、铜(Cu)、铁(Fe)、镁(Mg)、锰(Mn)、磷(P)、钾(K)、钠(Na)、锌(Zn)、铬(Cr)、钼(Mo)和硒(Se)的方法。该方法适用于婴儿配方奶粉和成人营养产品中12种元素的测定。 由于所有Cr结果均低于定量限且无法确定其重复性，因此本方法不适用于乳、奶粉、奶清粉、黄油和奶酪中的Cr检测。 本方法是对ISO 20649 | IDF 235 (AOAC 2011.19[2])的扩展，该标准仅在婴儿配方奶粉和成人营养产品中对Cr、Mo和Se进行了验证。 [外文原描述]： This document specifies a method for the quantitative determination of calcium (Ca), copper (Cu), iron (Fe), magnesium (Mg), manganese (Mn), phosphorus (P), potassium (K), sodium (Na), zinc (Zn), chromium (Cr), molybdenum (Mo) and selenium (Se) using inductively coupled plasma and mass spectrometry (ICP-MS). The method is applicable for the determination of all 12 elements in infant formula and adult nutritional products. The method is also applicable for milk, milk powder, whey powder, butter and cheese excluding the determination of Cr, because all Cr results were below the quantification limit and reproducibility could not be determined in these matrices [ 1 ] . The present method is an extension of ISO 20649 | IDF 235 (AOAC 2011.19 [ 2 ] ) which was validated only for Cr, Mo and Se in infant formula and adult nutritional products.
