摘  要:
[目的]建立一种高效液相色谱测定氯氟吡氧乙酸异辛酯含量的分析方法。[方法]采用高效液相色谱法,使用ZORBAX SB C18色谱柱,以甲醇-水(体积比80∶20)为流动相,流速为1 mL/min,在235 nm波长下氯氟吡氧乙酸异辛酯进行定量分析。[结果]当氯氟吡氧乙酸异辛酯质量浓度在120~660 mg/L范围内,方法的线性相关系数为1,标准偏差为0.27,变异系数为0.27%,平均回收率为99.7%。[结论]方法准确、快速,适用于氯氟吡氧乙酸异辛酯的定量分析。

摘  要:
[Aims]A HPLC method was developed for the quantitative determination of fluroxypyr-mepthyl. [Methods] The content of active ingredient in fluroxypyr-mepthyl was determined quantitatively by HPLC with the ZORBAX SB C 18 column at UV 235 nm, and methanol-water(80∶20, by vol) as the mobile phase at a fl ow rate of 1 mL/min. [Results][Results] The assay exhibited a good linearity in fl uroxypyr-mepthyl concentration range from 120 to 660 mg/L with a coeffi cient of 1. The standard deviation was 0.27, the variation coeffi cient was 0.27% and the average recovery was 99.7%. [Conclusions][Conclusions] The simple and accurate method is suitable for the quantitative analysis of fl uroxypyr-mepthyl.
