    R.J. Reynolds Tobacco Company, R&D, Bowman Gray Technical Center, Winston-Salem, NC, USA
    An analytical procedure was developed for the extraction and quantification of tobacco specific nitrosamines (TSNA): N'-nitrosonornicotine (NNN), N'-nitrosoanatabine (NAT), N'-nitrosoanabasine (NAB), and 4-(methylnitrosamino)-1-(3-pyridyl) ...

    RISNER C.H.; PARSONS S.V.; WINKLER L.S.
    R.J. Reynolds Tobacco Company, Bowman Gray Technical Center, Winston-Salem, NC, USA
    A method was developed that determines the scopoletin content of mainstream cigarette smoke. A Cambridge pad containing the wet total particulate matter (WTPM) of five cigarettes was extracted with 1% acetic acid (HAc), and the extract was subjected to ...

    Collection and ion chromatographic determination of nitrous acid in air

    RISNER C.H.
    R.J. Reynolds Tobacco Company, Bowman Gray Technical Center, Winston-Salem, NC, USA
    An active sampling method based on a solid-phase collection medium was used to determine nitrous acid concentrations in indoor air. A carbonate-bicarbonate coated filter was found to be inefficient for collection of nitrous acid. An amino type, weak anion ...

    Development of a theoretical model to predict the efficiency of flavor adsorption for tobacco cut-filler

    NAKANISHI Y.
    Japan Tobacco Inc., Tobacco Science Research Center, Yokohama, Kanagawa, Japan.
    Historically, processes for the application of volatile flavors to tobacco cut-filler materials has depended solely on an adsorption process. Results from the author's study, employing both theoretical and empirical approaches, have indicated that ...
