标准范围

ISO 27085:2009规定了一种电感耦合等离子体原子发射光谱（ICP-AES）法，用于测定:a）动物饲料中的矿物质钙、钠、磷、镁和钾以及元素铁、锌、铜、锰、钴和钼；b） 在用于动物饲料的预混料或混合物中，矿物质中的砷、铅和镉元素会单独存在。每个元素的方法检测限取决于样品矩阵和仪器。该方法不适用于低浓度元素的测定。定量限为3 mg/kg或更低。

ISO 27085:2009 specifies an inductively coupled plasma atomic emission spectroscopic (ICP-AES) method for the determination of: a) the minerals calcium, sodium, phosphorus, magnesium and potassium and the elements iron, zinc, copper, manganese, cobalt and molybdenum in animal feeding stuffs; b) the elements arsenic, lead and cadmium in minerals on their own, in premixtures or mixtures for use in animal feeding stuffs.The method detection limit for each element is dependent on the sample matrix as well as on the instrument. The method is not applicable for determination of low concentrations of elements. The limit of quantification is 3 mg/kg or lower.
