Selective Removal of Semivolatile Components of Cigarette Smoke by Various Filters

Abstract

The semivolatile portion of cigarette smoke contains acidic, basic, and neutral compounds that are important to the flavour and in some cases the physiological effects of smoke. A rapid method that could be used routinely for the gas chromatographic analysis of this portion of smoke was developed. A 160 mm glass capillary column was used to resolve approximately 150 semivolatile smoke components. Gas chromatography - mass spectrometry was used to identify about 35 of these components. Twenty known semivolatile compounds with different functional groups and boiling points were used to determine the effects of various filters on their removal from smoke. Standard cellulose acetate filters, cellulose acetate filters with glycerin, cellulose acetate filters with PEG 600, and cellulose acetate filters with activated carbon were evaluated. The cellulose acetate filters with glycerin and PEG 600 were more selective for the removal of aromatic hydrocarbons than were the standard cellulose acetate filters. The cellulose acetate filters with activated carbon were more selective for the removaI of the low-boiling semivolatile compounds than were the other filters tested.

Smoke composition and predicting relationships for international commercial cigarettes smoked with three machine-smoking conditions

“…It is well known that carbon has the potential to selectively adsorb many vapor-phase constituents from mainstream smoke (Baggett and Morie, 1975;Williamson et al, 1965). These carbon-filter cigarettes tended to be over-predicted, therefore contributing to larger average ARPEÕs, for several vapor-phase constituents since the majority of exploratory cigarette filters did not contain carbon.…”

Mainstream smoke constituent yields and predicting relationships from a worldwide market sample of cigarette brands: ISO smoking conditions

“…It is well known that carbon, i.e., activated charcoal, has the potential to selectively adsorb many vapor-phase constituents from mainstream smoke (Baggett and Morie, 1975;Williamson et al, 1965). Carbon monoxide and oxides of nitrogen are generally not affected by carbon (Tiggelbeck, 1972).…”

Pressure and Gas Flow Distribution Inside the Filter of a Non-Filter Ventilated Lit Cigarette During Puffing

“…A significant degree of selective filtration (i.e., certain chemical classes of aerosol components are retained better than the average aerosol filtration efficiency) has also been noted, especially for the semi-volatile fraction of the cigarette smoke components such as phenolic compounds (9,10). This chemistryrelated filtration is thought to occur due to a portion of the smoke compounds present in the vapour phase.…”
