滤嘴通风率对卷烟主流烟气有机酸释放量的影响研究

为考察滤嘴通风率对卷烟主流烟气有机酸释放量的影响,制备不同滤嘴通风率的卷烟样品,利用GC-MS法分析卷烟样品主流烟气中的有机酸,结果表明,(1)开发的GC-MS分析方法准确性和重复性好,能够满足卷烟烟气中有机酸释放量的准确测定;(2)随滤嘴通风率的增加,有机酸实际释放量和单位焦油释放量均明显降低,分子量较小的有机酸其单支释放量和单位焦油释放量降低率较低,而相对分子量较大的有机酸单支释放量和单位焦油释放量降低率较高。

In order to investigate the effect of filter ventilation rate on the release of organic acids from mainstream cigarette smoke, cigarette samples with different filter ventilation rates were prepared and the organic acids in mainstream cigarette smoke were analyzed by GC-MS. The results show that:(1) the developed GC-MS analysis method has good accuracy and repeatability and can meet the accurate determination of organic acid release from cigarette smoke;and(2)with the increase of filter ventilation rate, the actual release amount of organic acid and unit tar release decreased significantly, and the reduction rate of single branch release and unit tar release of organic acid with lower molecular weight was lower than that of organic acid with higher molecular weight.
