高效液相色谱法测定氰戊菊酯的含量

HPLC Determination of Fenvalerate

介绍了高效液相色谱法测定氰戊菊酯的方法。试样溶解于甲醇,试样中氰戊菊酯在250mm×4.0mm(i.d.)不锈钢柱,内装YWGC18填充物(10祄),以甲醇-水为流动相,以紫外为检测器,在254nm下进行分离和测定。方法回收率在99.8%￣101.2%之间。线性相关系数0.9998。方法的标准偏差和变异系数分别为0.0172和0.253%。

This paper describes an analytical method for fenvalerate determination by HPLC. The sample is dissolved in methanol, and fenvalerate in the sample is separated and determined using a 250× 4.0 mm (i.d.) stainless steel column packed with YWG C18 (10 祄), with methanol-water as the mobile phase and UV detection at 254 nm. Recovery ranged from 99.8%￣101.2%. The linear correlation coefficient was 0.9998. Standard deviation and coefficient of variation for the method were 0.0172 and 0.253%, respectively.
