气相色谱法测定大隆毒饵中的甘氟和氟乙酰胺

Analysis of gliftor and fluoroacetamide in brodifacoum bait by gas chromatography

用气相色谱法对大隆毒饵中的甘氟和氟乙酰胺进行了联合分析。毒饵用索氏提取器提取 ,以异丙醇为内标 ,在GDX 1 0 2色谱柱上进行分离 ,氢焰离子检测器。方法的平均回收率分别为 :甘氟Ⅰ :98.3% ,甘氟Ⅱ :97.7% ,氟乙酰胺 :98.2 % ,相对标准偏差分别为 1 .0 % ,1 .5 % ,1 .0 % (n =1 0 )

The method for determination of gliftor and fluoroacetamide in brodifacoum bait by GC was studied. The determination was carried out using a GDX 102 packed column. The operation was at 145℃. Both FID detector and injector port were set at 180℃. Isopropyl alcohol was used as internal standard. The average recovery of gliftor Ⅰ, gliftor Ⅱ, fluoroacetamid were 98 3%, 97.7%, 98.2% with RSD( n =10) of 1 0%, 1.5% and 1.0%, respectively.
