摘要
通过试验对GB/T 22388-2008《原料乳与乳制品中三聚氰胺检测方法》第一法——高效液相色谱法中的流动相p H、流动相的比例、蛋白沉降剂三个方面进行了改进和优化。试验结果表明:改进和优化后的方法灵敏度高、稳定性好,回收率达到97%以上,相比原方法具有明显的优势,值得推广应用。
Through the experiment of GB/T 22388-2008 ＂Determination of melamine in raw milk and dairy products＂ in the first method the method of HPLC mobile phase pH, mobile phase ratio, protein precipitation agent and three aspects of improvement and optimization, experimental results show that the sensitivity method to improve and optimize the high. Good stability, recovery rate of more than 97%, has obvious advantages than the original method, it is worthy of popularization and application.
