【摘要】 介绍了以四氢呋喃和水为流动相,使用以Kromasil C18为填料的不锈钢柱和紫外检测器,在240nm对试样中的喹禾灵、三氟羧草醚、异噁草松进行高效液相色谱分离和定量分析的方法。结果表明,喹禾灵、三氟羧草醚、异噁草松的线性相关系数分别为0.9994、0.9991、0.9992,标准偏差分别为0.008、0.018、0.031,变异系数分别为0.54%、0.18%、0.66%,回收率在98.0%～100.9%之间。更多还原

【Abstract】 Quantitative analysis was conducted on the active ingredients in a package mix formulation of quizalofop, acifluorfen and clomazone using HPLC with kromasil C18 column, a UV detector, a mobile phase of tetrahydrofuran- water. The correlation coefficients were 0.9994, 0.9991 and 0.9992 for quizalofop, acifluorfen and clomazone, respectively. SDS and RSDS were 0.008, 0.018, 0.031 and 0.54%, 0.18%, 0.66%, respectively. The recoveries were in range of 98.0% to 100.9%.更多还原
