本文叙述了采用气相色谱法即以5%XE-60/ChromosorbW/AW-DMCS(154~180μm)玻璃柱和氢火焰离子化检测分离测定20%哒·水胺乳油中的哒螨灵和水胺硫磷的含量。结果表明,哒螨灵和水胺硫磷的标准偏差分别为0.0286、0.0550;变异系数分别为0.5575%、0.3607%;平均回收率分别为99.69%、99.63%;线性相关系数分别为0.9998、0.9997。
This paper describes the separation and determination of pyridaben and water amine in 20% daunctam EC by gas chromatography with glass column of 5% XE-60 / ChromosorbW / AW-DMCS (154 ~ 180μm) and hydrogen flame ionization Phosphorus content. The results showed that the standard deviations of pyridaben and isocarbophos were 0.0286 and 0.0550, respectively. The coefficients of variation were 0.5575% and 0.3607% respectively. The average recoveries were 99.69% and 99.63% respectively. The linear correlation coefficients were 0.9998 and 0.9997.
