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

The particulate phases delivered from cigarettes containing 100 % Cytrel, 100 % flue-cured tobacco, and blends of Cytrel and tobacco have been extensively characterized. Approximately 70 % of Cambridge particulate matter (CPM) from 100 % Cytrel cigarettes has been defined. A considerably smaller fraction of CPM from 100 % tobacco cigarettes has been similarly defined because of its greater complexity. Only two of the components observed in the particulate phase, glyceroI and possibly sodium, were delivered in higher amounts by 100 % Cytrel cigarettes than by 100 % tobacco cigarettes. For all other species deliveries were lower from 100 % Cytrel cigarettes. In cigarettes containing blends of Cytrel and tobacco the deliveries of alI components were shown to follow an approximately linear relationship with blend level.
