    A liquid chromatography procedure for analysis of nicotine on cellulose acetate filters

    GREEN C.R.; CONRAD F.W.; BRIDLE K.A.; BORGERDING M.F.
    R.J. Reynolds Tobacco Company, R&D, Winston-Salem, NC, USA
    Nicotine is an important constituent of tobacco and tobacco smoke. Because of this, numerous analyses of this alkaloid have been developed. Procedures for measurement of leaf and smoke nicotine are well established, and their accuracy and reliability...

    Applications of pyrolysis-gas chromatography-mass spectroscopy to tobacco chemistry

    THOME F.A.; YOUNG G.W.; HAMLIN W.C. JR.
    R.J. Reynolds Tobacco Company, R&D, Winston-Salem, NC, USA
    Studies have been carried out using pyrolysis-gas chromatography-mass spectroscopy as an analytical technique that requires a small sample (milligram range) to produce a rapid and reproducible evaluation of individual tobaccos and blends. The...

    The effects of cigarette paper permeability and air dilution on carbon monoxide production and diffusion from the tobacco rod

    TOWNSEND D.E.; NORMAN A.B.
    R.J. Reynolds Tobacco Company, R&D, Winston-Salem, NC, USA
    A method for the direct measurement of CO diffusion through cigarette paper was developed. Diffusing gases from a lit cigarette were trapped in a plastic sample bag and subsequently analyzed on a non-dispersive infrared analyzer (NDIR) having a 0-2%...
