摘要
采用高效液相色谱–串联质谱法检测玉米中的黄曲霉毒素B1。对样品前处理条件、净化和分离条件进行了优化,黄曲霉毒素B1检出限为0.02μg/kg,回收率为83.8%～95.7%。建立的方法简便、快速、灵敏度高,能够满足玉米中痕量黄曲霉毒素B1农残的高灵敏测定要求。
An analytical method for the determination of aflatoxin B 1 in corn by ultra-high performance liquid chromatography tandem mass spectrometry was developed. Sample pretreatment methods and depuration conditions were optimized. The detection limit of aflatoxin B1 was 0. 02 μ g/kg. The recoveries were 83.8% - 95.7%. The results indicated that the method developed is simple, rapid, sensitive, which is suit for the analysis of aflatoxin B1 pesticides in corn.
