【摘要】 采用毛细管气相色谱法 ,以邻苯二甲酸二丁酯为内标 ,对乙氧氟草醚进行定量分析。色谱条件为 6 0 m×0 .5 3mm I.D.) ,膜厚 1.5︼m (SE- 30固定液 )熔融石英毛细管柱 ,柱温为 2 30℃ ,检测器、汽化室温度为 2 5 0℃ ,载气 N2 的流速为 15 m L· m in- 1 。乙氧氟草醚的标准偏差为 0 .4 7,平均变异数为 0 .88% ,平均回收率为 10 0 .13%。此定量方法能分开乙氧氟草醚的二个同分异构体 ,操作简便、结果准确更多还原

【Abstract】 A method was described for the determination of oxyfluorfen by capillary gas chromatography with FID on SE 30 60 m capillary column,using Dibuty o phthalate as internal standard.The standard deviation for oxyfluorfen were 0.47.The coefficients of variation for xoyfluorfen concentration were 0.88%,the average recoveries for oxyfluorfen were and 101.10%.This method is simple,rapid and good in accuracy.更多还原
