GC-MS Determination of Components in Particulate and Gaseous Matters of Mainstream Smoke of Cigarette

The particulate matters in mainstream smoke of cigarettes were trapped by Cambridge filter, and the gaseous mathers were absorbed by cold trap-solvent method. The particulate matters on the filter were extracted with methanol. The components in the absorbent and extract were separated individually on DB-WAX and determined by MS. It was found that: ① 75 components in gaseous matters and 60 components in particulate matter were identified; ② 17 compounds were found in both the phases of mainstream cigarette smoke; ③ most of the hydrocarbons were in the gaseous matters, with only a few in the particulate matters; ④ 5 phenols were found in gaseous matters only; ⑤ 21 benzenes were identified, which were found mainly in gaseous matters.
