    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. Prior ...

    Particle breakthrough comparison of commercial carbon filters with CelFX™ carbon/acetate filters

    ROBERTSON R.M.; SUTHAR J.N.; BASU S.
    Celanese, Narrows, VA, U.S.A.
    Previous works have evaluated cigarette filter carbon particle release from various filter designs. The recently introduced CelFX™ Matrix Technology offers high loadings of carbon, with low pressure drops and has not been studied for the particle release ...
