摘要:

为了建立气相色谱- 质谱检测进出口农产品中乙嘧酚磺酸酯的检测方法。样品经乙腈提取浓缩后,经固相萃取柱净化,以气相色谱- 质谱联用仪测定和确证,外标法定量。结果表明,方法检出限为0.01mg/kg,回收率为70.0%~89.5%,相对标准偏差为6.11%。本方法简便、快速、准确、可靠,可应用于农产品检测。

Abstract:

Bupirimate in agricultural products was extracted and concentrated with acetonitrile,and purified using solid phase extraction column. Then it was detected with GC-MS and quantified with external standard method. The limit of quantification was 0.01 mg/kg, and the recovery was in the range of 70.0%-89.5% with the relative standard deviation at 6.11%.

Key words: bupirimate, GC-MS, agricultural product
