摘要
本文介绍了用国产固相柱GDX403分析中毒后全血及毒饵中的毒鼠强。检测方法选用GC/NPD、毛细管色谱技术,咖啡因作内标。该方法具有灵敏、简单、快速、回收率高、稳定性好的特点。在1ml全血中加入1.0μg毒鼠强,回收率为83.7%,变异系数为4.61%。该方法是分析毒饵及中毒后全血中毒鼠强的有效方法。
This paper concerns determination of tetramine from whole blood and bait by using GDX-403 solid-phase extraction columns and capillary gas chromatography with nitrogen-phosphorus detector, caffein as internal standard. Add 1.0μg of tetramine into 1ml of whole blood, the recovery is 83.7% with SD less than 3.68% and CV less than 4.61%.The method show sensitive、simple and satisfactory recovery with good reproducibility.
