本文采用高效液相色谱法,以C18柱为固定相,甲醇+水为流动相,用236nm紫外检测器定量测定唑禾草灵、乙羧氟草醚混剂的有效成分含量。本方法的变异系数分别为0.06%、0.40%;标准偏差分别为0.009、0.032;平均回收率分别为99.13%、100.05%;线性相关系数分别为0.9993、0.9998。
In this paper, high performance liquid chromatography, C18 column as the stationary phase, methanol + water as mobile phase, with the determination of 236nm UV detector oxazole grass Ling, fenvalerate mixture of active ingredient content. The coefficients of variation of this method were 0.06% and 0.40%, respectively. The standard deviations were 0.009,0.032 and the average recoveries were 99.13% and 100.05% respectively. The linear correlation coefficients were 0.9993 and 0.9998, respectively.
