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。
This paper introduces the use of tetrahydrofuran and water as the mobile phase, the use of Kromasil C18 as a filler stainless steel column and UV detector in the 240nm on the sample of quizalind, acifluorfen, clomazone high performance liquid chromatography Method of separation and quantitative analysis. The results showed that the linear correlation coefficients of quizalofop, acifluorfen and clomazone were 0.9994, 0.9991 and 0.9992, respectively. The standard deviations were 0.008, 0.018 and 0.031, respectively. The coefficients of variation were 0.54%, 0.18% and 0.66 %, The recovery rate between 98.0% ~ 100.9%.
