The Characterization of Cigarette Smoke from Cytrel^® Smoking Products and its Comparison to Smoke from Flue-Cured Tobacco: II. Semi-Volatile Phase Analysis

Major semi-volatile components from Cytrel cigarette smoke have been characterized and compared to the smoke from flue-cured tobacco cigarettes. Significantly greater numbers of cigarettes are required to produce the Cytrel scans due to the very low tar deliveries of these cigarettes. Even so, the CytreI scans are far simpler than those from tobacco-containing samples. Using triacetin delivered from the cigarette filters as an internal standard, numerical data have been derived to compare semi-volatile components from 100 % Cytrel with 100 % flue-cured tobacco and with a 50 % blend with tobacco on an approximately equal cigarette basis. Of the 128 semi-volatile components compared, 37 were found only in tobacco-containing samples and 66 others were present in significantly greater amounts in tobacco than in CytreI. No components were found in CytreI semi-volatiles that were not also present in tobacco smoke. GlyceroI, which is present in Cytrel smoke, does not appear in the 130°C semi-volatile fraction obtained by the capsule sampling technique.
