摘　　要：建立了气相色谱电子捕获器法检测卷烟抽吸过程中氟节胺向主流烟气总粒相物中转移量的方法，卷烟在标准条件下抽吸，用剑桥滤片捕集主流烟气总粒相物，经乙腈提取、石墨碳黑固相萃取柱或自制混合层析柱净化、GC／ECD检测后，外标法定量。氟节胺在0．02～20mg／L范围内线性关系良好，检出限为9．14×10^-6g/L。加标量为30μg/包时，卷烟抽吸过程中氟节胺向主流烟气总粒相物中转移量的平均加标回收率为88％～93％，相对标准偏差（RSD）为1．5％～2．8％，空白加标的平均回收率为94％～100％，相对标准偏差（RSD）为1．4％-2．4％。与传统的氟节胺检测方法相比，该方法操作简单、快速，准确性好且环保，可满足烟草中农药向主流烟气总粒相物中转移量的检测要求。A gas chromatographic method coupled with electron capture detection （GC/ECD） was developed for the determination of flumetralin deliver amount in total particulate matter（TPM） of mainstream cigarette smoke during cigarette smoking. Under the standard conditions, cigarette were smoked to collect the TPM of mainstream cigarette smoke with cambridge filter, and then extracted with acetonitrile. The extracts were cleaned up with the Supelclean^TM ENVI^TM-Carb SPE tubes or the mixed chromatography column, and determined by GC/ECD with the external standard method. The calibration curve was linear for flumetralin in the range of 0. 02 - 20 mg/L with a limit of detection （LOD） of 9. 14 × 10^-6 g/L. When a spiked level of flumetralin by 30 μg/bag was added, the mean recoveries of flumetralin deliver amount in TPM of mainstream cigarette smoke during smoking ranged from 88% to 93% with relative standard deviations （RSDs） of 1.5% -2. 8% . The average recoveries of flumetralin from spiked blank sample were in the range of 94% - 100% with RSDs of 1.4% - 2. 4% . Compared with the traditional methods, the proposed method was simple, rapid, accurate and environment-friendly. Therefore, it was suitable for the determination of flumetralin deliver amount in TPM of mainstream cigarette smoke during smoking.
