在三聚氰胺的检测中采用沉淀剂沉淀、微波超声、离心分离相结合的方法提取,用高效液相色谱法测定,再用保留时间定性,外标法定量。该方法能有效的排除乳制品中蛋白质、脂肪等大分子物质以及其它含氮物质对检测的影响,最低检测限为1.0mg/kg,回收率为98.0%～102.6%之间,因此能普及到乳制品的检验检测中。 In the melamine detection precipitation precipitator, microwave ultrasound, centrifugation combined with the method of extraction, determination by high performance liquid chromatography, and then retention time qualitative, external standard method. The method can effectively exclude the impact of protein, fat and other macromolecules and other nitrogenous substances in the detection of dairy products, the detection limit is 1.0mg / kg, the recovery rate is 98.0% ~ 102.6%, so it can be popularized Inspection and testing of dairy products.
