摘要

本文采用岛津公司的GPC-GC-MS/MS系统,在无需标准品的情况下,建立了筛查食品中非目标物农药残留的筛查方法.食品样品经简单前处理后,分别添加10种农残混标,采用所建立的MRM采集方法对目标组分进行灵敏度考察.在10μg·L~(-1)浓度下,食品样品中的10种常见农药残留均被筛查出来,且组分相应信号高.该方法简单易操作、灵敏度高,完全满足食品安全中农药残留筛查和检测的要求.
        Shimadzu′s GPC-GC-MS/MS system was used to establish a screening method for screening non-target pesticide residues in food without standard products. After simple pre-treatment, the food samples were added with 10 kinds of pesticide residues, and the sensitivity of the target components was investigated by the established MRM collection method. At 10 μg·L~(-1) concentration level, 10 common pesticide residues in food samples were screened and the corresponding signals were high. The method is simple and easy to operate, has high sensitivity, and fully meets the requirements for screening and testing pesticide residues in food safety.
