- 氯氰菊酯等拟除虫菊酯添加水平在0.5-2.00 mg/kg时,该方法回收率为80%-102%,精密度为4.88%-9.98%,方法测定低限为0.05 mg/kg,各项指标均满足有关要求。The extract was cleaned up with GPC and tested using GC-MSD with the quantitation by external standard method and positive confirmation by selected-ion monitoring mode. While 0.5mg/kg-2.00 mg/kg of cypermethin etc. pyrethroids were fortified,the recoveries of this method was from 80%25 to 102%25,precision was between 4.88%25 and 9.98%25,and the determination limit was 0.05 mg/kg.
