    A modelling approach to develop machine smoking protocols reflecting human puffing behaviour for conventional cigarettes

    URBAN H-J.; GOMME W.; SCHORP M.
    Philip Morris Intl, Philip Morris Product SA, R&D, Neuchâtel, Switzerland
    Our objective was to develop machine-smoking protocols (i.e. puff volume, puff duration and puff frequency) reflecting the distribution of human smoking behaviour as a complement to the International Standard (ISO) protocol. For this purpose, a modelling ...

    The ability of the FTC method to quantify nicotine as a function of ammonia in mainstream smoke

    CALLICUTT C.H.; COX R.H.; FARTHING D.
    Philip Morris USA, Research Center, Richmond, VA, USA
    Whether ammonia-forming ingredients added to tobacco and ammonia in smoke affect the ability of the Cambridge filter pad to trap nicotine in the Federal Trade Commission (FTC) method was examined. Three commercial cigarettes, two industry reference ...

    Application of nanoparticle iron oxide in cigarette for simultaneous CO and NO removal in the mainstream smoke

    PING L.; RASOULI F.; HAJALIGOL M.R.
    Philip Morris USA, Research Center, Richmond, VA, USA
    Based on the unique temperature and oxygen profiles in a burning cigarette, a novel approach is proposed in this paper to use a single oxidant/catalyst in the cigarette filler for simultaneous removal of carbon monoxide (CO) and nitric oxide (NO) in ...

    A mathematical scheme for calculating flows and pressure drops in lit and unlit cigarettes

    DWYER R.W.; CHEN P.; WASYK R.D.
    Philip Morris USA, Research Center, Richmond, VA, USA
    A computational methodology is presented for evaluating the flows and pressure drops in both lit and unlit cigarettes. The flows and pressure drops across rows of tipping-paper perforations are considered explicitly, as are the locations and relative ...
