| 摘 要： | 通过顶空固相微萃取进样器(HS-SPME)对卷烟主流烟气剑桥滤片中的游离烟碱进行萃取,并用气相色谱/质谱(GC/MS)进行外标法定量分析,对溶剂、萃取纤维、预平衡时间、萃取时间、萃取温度、脱附时间等分析条件进行了优化.同时建立了滤片不同含水量对游离烟碱测定影响的校正曲线,根据实际样品主流烟气粒相物水分的含量对游离烟碱的...

| Abstract: | An improved,rapid method to measure free-base nicotine in mainstream cigarette smoke accurately by commercial headspace solid phase microextraction(HS-SPME) combined with GC/MS was established.The factors which play important roles in the determination of free-base nicotine,such as the solvent used for preparation of standards,SPME fiber,pre-equilibrium time before HS-SPME,extraction temperature and time,desorption time,were optimized carefully.Furthermore,an experimental water correction factor based on th... |
