    Puff-by-puff tar, nicotine and carbonyl profiles under different smoking regimens of commercial cigarettes with various carbon filter technologies

    ROBERTSON R.M.; NORFLEET K.; CANTERBURY W.B.
    Celanese, Narrows, VA, U.S.A.
    Puff-by-puff smoke analysis has shown that the CelFX® carbon filter technology has similar nicotine and tar smoke delivery profiles but with significantly reduced carbonyls, particularly in the first 6 puffs, compared to a cellulose acetate filter....
