为实现烟草中四溴菊酯和溴氰菊酯的同时分析，利用QuEChERS前处理方法萃取烟草样品并对萃取液进行初步净化，采用弗罗里硅土固相萃取小柱对萃取液作进一步净化处理，采用超高效合相色谱仪（非极性的HSS C18 SB色谱柱作固定相，甲醇为流动相辅助剂）检测了四溴菊酯和溴氰菊酯。结果表明：四溴菊酯和溴氰菊酯残留量的分析可在6.5 min内完成，线性范围均为0.5~25.0 mg/kg，相关系数（R2）大于0.9995，平均加标回收率分别为92.6%和84.3%，相对标准偏差均小于10%，定量限分别为0.33和0.23 mg/kg。该方法弥补了气相色谱法不能检测四溴菊酯的不足。

In order to analyze the tralomethrin and deltamethrin in tobacco simultaneously, the extract was preliminarily purified after tobacco sample was extracted by QuRChERS pretreatment, the extract was further purified with Florisil solid phase extraction column. Tralomethrin and deltamethrin were determined by ultra performance convergence chromatography (UPC2) with non-polar HSS C18 SB column as solid phase and methanol as mobile phase auxiliary agent. The results showed that it only took 6.5 minutes to complete the analysis of tralomethrin and deltamethrin residues, the linear range of this method were 0.5-25.0 mg/kg with the correlation coefficient (R2) more than 0.999 5 and relative standard deviation less than 10%. The average standard addition recoveries and detection limits of tralomethrin and deltamethrin were 92.6%, 84.3% and 0.33, 0.23 mg/kg, respectively. This method advantages over gas chromatography, the later fails to detect tralomethrin.
