采用高效液相色谱法测定混剂中异丙草胺、异噁草松的含量。使用KromesilODS、5μm为填料的不锈钢柱,以甲醇+0.05%磷酸为流动相,检测波长215nm。结果表明,该方法测得异丙草胺、异噁草松的标准偏差为0.24、0.11,变异系数为0.53%、0.51%,线性相关系数为0.9998、0.9993,回收率为99.9%、99.3%。 The contents of isopropylamine and clomazone in the mixture were determined by HPLC. Using KromesilODS, 5μm stainless steel column packed with methanol + 0.05% phosphoric acid as the mobile phase, the detection wavelength of 215nm. The results showed that the standard deviation of isopropamide and clomazone were 0.24 and 0.11, the coefficients of variation were 0.53% and 0.51%, the linear correlation coefficients were 0.9998 and 0.9993, the recoveries were 99.9% and 99.3% respectively.
