Study on the Microinfrared Spectroscopy of Smoke Aerosols from Different Series Cigarettes of the Same Brand
[Objective]Based on FTIR microspectroscopy of the smoke aerosols of the same brand from different series of cigarettes,quick dif-ferentiation model was established.[Method]FTIR microspectroscopy was used to determine the smoke aerosols of different series of cigarettes from the same brand.A model was established by using principal component analysis(PCA).The nicotine content,moisture content,tar con-tent,and carbon monoxide amount in the smoke were compared with the traditional methods.[Result]FTIR spectroscopy analysis results re-vealed that H7,H11,H12,B1,B13,and B14 were far away from other samples,which were consistent with the determined results by traditional methods.[Conclusion]FTIR microspectroscopy can quickly distinguish the smoke aerosols from different series of cigarettes of the same brand,which provided a new method for the quality identification of cigarettes.
