【摘要】 为考察不同捕集方式下卷烟主流烟气成分的差异,分别采用剑桥滤片和静电捕集器两种捕集方式对卷烟主流烟气的粒相物部分进行捕集,并采用GC/MS法对卷烟主流烟气中的半挥发性成分中的碱性和中性物质进行分析。结果表明,对于中性和碱性香味成分,两种捕集方式获得的成分种类和含量都具有一定的差异,而且对于大多数化合物而言,剑桥滤片的捕集效率要高于静电捕集,这与两者的捕集原理相关。更多还原

【Abstract】 In order to investigate the influence of smoke traps on the components of mainstream smoke,the total particulate matters were collected with Cambridge filter and electrostatic trap,respectively.The semi-volatiles were determined by gas chromatography-mass spectrometry.The results show that the kinds and yields of aroma components are different between electrostatic trap and Cambridge filter.更多还原
