摘要
采用反相高效液相色谱外标法,以甲醇-水作为流动相,用C18柱和紫外检测器(237 nm)测定了40%喹草酮·异丙甲草胺悬浮乳剂的含量。结果表明:方法的标准偏差为0.017、0.051;变异系数为0.34%、0.14%;平均回收率为99.40%、99.33%;线性相关系数为0.9998、0.9997。
A quantitative analytical method of 40% quinotrione and metolachlor SE by RP-HPLC was described.Using methanol∶water∶acetic acid=88∶12∶0.1(V/V)as mobile phase,using Kromasil C18 column at UV detector(237 nm).The results showed that the standard deviation,the coefficient of variation,the average recovery and the liner correlation of quinotrione and metolachlor were 0.017,0.34%,99.40%,0.9998 and 0.051,0.14%,99.33%,0.9997,respectively.
