摘 要:【目的】实现加热卷烟中多种农药残留的测定。【方法】样品经乙腈提取,以PRiME HLB通过式固相萃取柱净化后,分别以液相色谱-串联质谱(LC-MS/MS)和气相色谱-串联质谱(GC-MS/MS)分析。【结果】①PRiME HLB通过式固相萃取净化效率高,操作简便。②在高、中、低三个不同添加浓度水平下,所有分析物的回收率在77.36%~108.28%之间,相对标准偏差(RSD)小于8.0%。所有农药均获得了良好的线性相关系数(r≥0.9977),检出限(LOD)和定量限(LOQ)范围分别为0.31~10.88μg/kg和1.11~36.21μg/kg。③采用该方法对25个实际样品进行了检测,所有样品均检出有杀菌剂。【结论】该方法操作简便,结果准确可靠,可用于测定加热卷烟中的多种农药残留。[Objective]In order to realize the determination of multiple pesticide residues in heated cigarettes.[Methods]The samples were extracted with acetonitrile,purified by PRiME HLB pass-through solid phase extraction,and analyzed by LC-MS/MS and GC-MS/MS,respectively.[Results]①The purification efficiency of PRiME HLB pass-through solid phase extraction is high and the operation is simple.②Under high,medium and low levels of addition concentration of,the recoveries of all compounds were 77.36%-108.28%,with relative standard deviations(RSDs)less than 8.0%.Good linear correlation coefficients were obtained(r≥0.9977)for all studied analytes.The LOD for all analytes varied from 0.31-10.88μg/kg and the LOQ varied from 1.11-36.21μg/kg.③Twenty five actual samples were tested using this method,and all samples were found to be contaminated by fungicides.[Conclusion]The method is simple to operate,accurate and reliable,and can be used for the determination of multiple pesticide residues in heated cigarettes.
