摘要
本文报道采用Nova-PakC18不锈钢色谱柱进行反相液相色谱分析,以V(甲醇)∶V(水)=65∶35(pH=3)为流动相,以邻苯二甲酸二乙酯为内标物,用内标法测定田草净除草剂中绿黄隆和异丙甲草胺的含量。结果表明,各有效成分与内标物色谱峰分离完全,杂质无干扰,测定结果,绿黄隆和异丙甲草胺的变异系数为1.14%和0.50%。回收率分别为:99.0%~101.4%和98.3%~100.6%
This paper indroduced a high performance liquid chromatography method to determine two active ingredients of maicaojing.Consisting of chlorsufuron and metolachlor was described.Chromatographic conditions were:column,Nova-pak,C18,5,4.6mm150mm;mobile phase,V(CH3OH)V(H2O)=6535.
