酸奶饮料中三聚氰胺的高效液相色谱法分析

Analysis on Melamine in Acidophilus Milk Beverages by HPLC

用高压液相色谱法测定了酸奶饮料中三聚氰胺的含量．结果表明：在0．1～1．6μg／mL范围内三聚氰胺与峰面积呈良好线性关系，相关系数为0．9973，回归方程为：A=59746C＋183．48，回收率为98．1％-99．0％，变异系数小于1．52％．

HPLC is used for the determination of melamine in acidophilus milk beverages. The results show that the linear range of melamine is between 0.1 - 1.6 μg/mL with a correlation coefficient of 0.997 3 and the regression equation being A = 59 746 C ＋ 183.48, and recovery of the method is 98.1% - 99.0% and RSD less than 1.52 %.
