电子烟液中烟碱稳定性及其释放行为分析

摘要

对7种品牌市售电子烟及30种电子烟液,从烟液烟碱含量、单次充电最大抽吸口数、烟碱释放行为进行了分析比较,为深入研发电子烟产品提供数据参考.结果表明:①电子烟液常温放置半年,具有良好的稳定性;②电子烟液的实测值和盒标烟碱值差异较大;③不同品牌电子烟电池容量差异较大,可抽吸口数在50-420之间;④抽吸时烟弹中可释放烟液量和烟杆中电池电量对烟碱释放行为有明显影响.%Data reference was provided for further research and development of electronic cigarette products. Seven brands of commercial e-cigarettes and 30 e-liquids were compared in terms of maximum puff number of battery, nicotine content and its release behavior. Results showed that: (1) E-liquids were highly stable under natural temperature in six months. (2) Due to lack of regulations, e-liquids may contain inaccurately labelled nicotine levels. (3) Puffnumber based on battery capacity was in the range of 50-420. (4) Releasable nicotine in cartridges and battery energy had a signifi cant influence on release behavior of nicotine.
