    A high performance liquid chromatographic method to quantify phenolic compounds in an isopropanol extract of mainstream cigarette smoke

    PRAKASH A.; IRELAND M.S.
    Lorillard Tobacco Company, Greensboro, NC, USA
    A high performance liquid chromatographic (HPLC) method was developed to quantify hydroquinone, catechol, and phenol in the isopropanol extract of mainstream cigarette smoke. This method reduces sample preparation, because the same isopropanol...

    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...

    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...
