| 摘 要： | 比较了超高效液相色谱-串联质谱(UPLC-MS/MS)与高效液相色谱(HPLC)法测定茶叶中10种氨基甲酸酯类农药残留的分析方法。样品经乙腈提取,氨基固相萃取柱净化,HPLC和UPLC-MS/MS测定。结果表明,在相同的前处理条件下,两种方法均具有较好的准确度和精密度,UPLC-MS/MS法在0.01~0.1mg/kg添加水平下回收率为75.2%~115.6%,相对标准偏差(RSD)为4.4%~16.7%。HPLC法在0.05~1.0mg/kg添加水平下回收率为82.7%~120.7%,相对标准偏差(RSD)为0.8%~12.9%。UPLC-MS/MS法相对于HPLC法有更高的灵敏度,10种氨基甲酸酯类农药在UPLC-MS/MS上检出限为0.02~0.3μg/kg,HPLC法检出限为3~7.5μg/kg;其高灵敏度和选择性,使其更适于多农药残留同时检测和微量残留检测。
