摘要
叙述了采用高效液相色谱外标法,以甲醇-水-三乙胺作为流动相,用C18柱和紫外检测器(215nm),测定了可乐饮料中4-甲基咪唑的含量。结果表明:方法的检测限为0.05mg/kg,变异系数为4.2%,平均回收率为95.89%,线性相关系数为0.9994。
A quantitative analytical method of 4-Methylimidazole in Beverage with SPE by HPLC was described. Using acetonitrile：water： triethylamine =30：70：1.6（V/V） as mobile phase, using Kromasil C18 column at UV detector （215nm）. The results showed that the limits of detection, the coefficient of variation, the average recovery and the liner correlation of method were 0.05mg/kg, 4.2%, 95.89% and 0.999 4 respectively.
