摘　　要：为准确测定加热卷烟气溶胶中的水分和焦油,设计并开发了吸烟机捕集器原位萃取仪,通过在加热卷烟抽吸后,直接进行金属捕集器内部原位萃取,建立原位萃取-气相色谱测定加热卷烟气溶胶中水分的分析方法。结果表明:(1)方法的回收率在95.4%~104.6%之间,RSD在3.72%~6.09%之间,检出限为0.16 mg/支。(2)与传统的振荡萃取法相比,在ISO抽吸模式下原位萃取法的水分测定值增加15.95%~22.16%,HCI抽吸模式下增加38.34%~40.37%。(3)原位萃取不影响烟碱、1,2-丙二醇和丙三醇等加热卷烟气溶胶主要成分的测定;原位萃取同样也适用于传统卷烟烟气焦油释放量的测定。该方法适用于加热卷烟气溶胶中水分、焦油、烟碱、1,2-丙二醇和丙三醇的准确测定。In order to accurately determine the release of moisture and tar in the aerosol of heated tobacco products, an in situ extraction device with a smoking machine trap was designed and tested.The aerosol produced by machine-smoking a heated tobacco product was collected, the Cambridge filter pad inside a bespoke metallic trap was directly extracted and then the moisture was analyzed by GC. The results showed that: 1) The recoveries of the in situ extraction method were in the range of 95.4%-104.6% and the relative standard deviations(RSDs) ranged from 3.72% to 6.09% with the limit of quantification of 0.16 mg/cigarette. 2) Comparing with conventional vibrating extraction, the moisture content in the aerosol determined by the in situ extraction method increased by15.95%-22.16% under the ISO puffing regime and 38.34%-40.37% under the HCI puffing regime.3) The main components, such as nicotine, 1,2-propylene glycol and glycerol, in the aerosol of the tested heated tobacco products were not affected by the in situ extraction method. This method was also applicable to the determination of tar release in the smoke of conventional cigarettes. This method could be used for the accurate determination of moisture, tar, nicotine, 1,2-propylene glycol and propanetriol in the aerosol of heated tobacco products.
