对氯苯氧乙酸钠水剂的液相色谱分析

The Quantitative Ananlysis of Sodium 4-CPA AS by HPLC

叙述了采用高效液相色谱法以甲醇+水+冰乙酸=80+20+0.05(V+V)为流动相,通过C18色谱柱和二极管阵列检测器对0.11%对氯苯氧乙酸钠水剂中的对氯苯氧乙酸钠进行分离和测定,结果表明标准偏差0.023,变异系数为2.01%,平均回收率为98%,线性相关系数为0.9994。

The quantitative analysis of sodium 4-CPA was introduced by reverse phase HPLC, using MeOH, water and glacial acetic acid （80＋20＋0.05）, pH=3 as mobile phase, using C18 column and DAD. the results showed that the standard deviation for sodium 4-CPA was0. 023, the variation coefficient was 2.01%, liner correlation was 0. 999 4.
