8种中心电加热卷烟烟气释放特性分析

Analysis for smoke release characteristics of several central electrical heated cigarettes

目的:探寻中心电加热卷烟烟气释放特性的共同点及差异性。方法:采用气相色谱分析了7款国产境外上市电加热卷烟(卷烟A-G)和1款市售国外电加热卷烟(卷烟H)主流烟气总释放量、逐口释放量及其释放稳定性,并对可能影响其稳定性的退丝率因素进行了探讨。结果:①卷烟H主流烟气中烟碱、甘油转移率均最低;②卷烟H烟气释放稳定性最高;③中心电加热卷烟烟气逐口释放量均随抽吸口序的增加整体呈先上升后逐渐下降趋势,中间略有波动,与传统卷烟在ISO模式下逐口释放规律有所区别;④烟支在插入中心加热烟具时产生的退丝现象对卷烟烟气释放稳定性有不利影响。结论:减少中心电加热卷烟的退丝现象可以提高烟气释放稳定性。

Objective:Studied the smoke emission characteristics of central electric heating cigarette.Methods:The release amount and stability of total and puff-by-puff mainstream smoke were investigated by taking seven domestic cigarettes(Cigarettes A-G)and one foreign cigarette(Cigarette H)as the samples.The factors that may influence smoke release stability were discussed.Results:①The transfer ratios of nicotine and glycerol in Cigarettes H were the lowest;②The smoke release stability of Cigarettes H was the highest;③The release behavior of TPM,nicotine and glycerol on a puff-by-puff basis all showed increase-decrease trend with the increase of puff sequence,which was different from the traditional cigarettes under ISO regime;④The tobacco retreated phenomenon when cigarette was inserted into its heating device had negative effect on the smoke release stability.Conclusion:The smoke release stability could be improved by reducing the tobacco retreated phenomenon of central electric heating cigarette.
