摘要
[目的]用显微红外光谱测定同一品牌不同系列卷烟的烟气气溶胶,建立快速区分模型.[方法]利用显微红外光谱测定同一品牌不同系列卷烟的烟气气溶胶,应用主成分分析(PCA)建立模型,并与传统方法测定的烟气烟碱量、烟气水分、焦油量、一氧化碳量进行比较.[结果]显微红外光谱分析结果显示,H7、H11、H12、B1、B13和B14与其他样本距离较远,与传统方法测定结果基本吻合.[结论]显微红外光谱能快速区分同一品牌不同系列卷烟的烟气气溶胶,为卷烟的品质鉴定提供了一种新方法.
Abstract
[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.
