摘　　要：为探索雾化温度对电子烟油雾化主产物的影响,测量了15种可充电电子烟的雾化温度等参数,利用热裂解仪模拟雾化器,在线气相色谱-质谱法分析考察了雾化温度改变对电子烟烟油雾化主产物的影响。结果表明,15种电子烟雾化温度范围为78~288℃,相差210℃;烟油在雾化过程中可以释放出1,2-丙二醇、甘油和烟碱,这3种物质组成了电子烟烟油雾化后的主要产物,三者含量之和在80、150、250、300、500和900℃雾化条件中分别占总量的99.66%、96.66%、99.53%、99.35%、97.25%和98.92%;雾化温度80℃时烟油雾化产物中未发现甘油,而且随着温度升高一直是1,2-丙二醇的相对含量高于甘油,直至雾化温度达到900℃时甘油的相对含量高于1,2-丙二醇。For exploring the effects of atomization temperature on major products of electronic cigarette liquids, the main parameters of 15 kinds of rechargeable electronic cigarettes were measured,and Py-GC / MS were applied to analyze the effects of atomization temperature variation on major products of electronic cigarette liquids. Results indicated that : 1The atomization temperature of 15 kinds of rechargeable electronic cigarettes were ranged from 78 ℃ to 288 ℃, the difference was 210 ℃ between the highest and lowest temperature. 2 Propylene glycol, glycerin and nicotine were released from electronic cigarette liquids in the atomization process and constituted three major products after the atomization,total relative content of these three products were 99.66%,96.66%,99.53%,99.35%,97.25% and 98.92% under atomization temperature of 80,150,250,300,500 and 900 ℃,respectively. 3 Glycerin wasn't found in atomization products at atomization temperature of 80 ℃. With the increase of temperature,the relative content of propylene glycol was always higher than glycerin,but it was reversed at atomization temperature of 900 ℃.
