CelFX™ carbon technology: puff-by-puff profile

Celanese, Narrows, Virginia, USA

CelFX™ carbon filter technology has been shown to reduce vapor phase smoke components by 40-90% in prior work[1]. In order to expand the understanding of this filtration performance, this work will evaluate the puff-by-puff machine profile to assess the filter performance on individual puffs. It is known that nicotine or tar delivery from the first puff is different than the last puff. This work will seek to assess the effect on that puff profile from presenting the carbon to the smoke in a much more efficient and higher loading format. Carbonyls and volatile compounds will be tracked and compared against a cellulose acetate filter control (Kentucky 3R4F cigarettes).
