    Determination of nicotine in smoke condensate by ion chromatography coupled to ultraviolet detection

    GEISS O.; KOTZIAS D.
    European Commission, Joint Research Centre, Institute for Health and Consumer Protection, Ispra (Va), Italy
    A new method for the determination of the nicotine content of tobacco smoke condensate is described. The smoke condensate of the mainstream smoke was collected in a glass fibre filter trap and dissolved in isopropanol. The nicotine content of an...

    A model for the prediction of tobacco temperature and oxygen profiles in warehouse aging process

    ZHEN Y.; CHIPLEY J.; DOW A.
    U.S. Smokeless Tobacco Inc, Nashville, TN, USA
    A mathematical model on the temperature and oxygen profiles for the tobacco warehouse aging process was formulated and solved by numeric analysis. The mode parametres were obtained using the non-linear regression method by fitting several years...
