    Characterization of flavor transfer during smoking of cigarettes with flavor capsules and aromatized tobacco cigarettes using SPME-GCMS

    RUFENER C.; BANCHERO M.; UMPIERREZ E.; BENSE T.
    C.I.T. Montepaz S.A., Montevideo, Uruguay
    Flavored tobacco has been used in cigarettes for many decades, but nowadays consumption of flavor capsule cigarettes is increasing in South American markets. Flavor capsules give the smoker the option of choosing to smoke the cigarette with or without ...

    Method development for pH analysis of ends aerosol and e-liquid

    HEFNER T.(1); ST. CHARLES F.K.(2); ANDERSON J.(3)
    (1) R.J. Reynolds Tobacco Company, Winston Salem, NC, USA; (2) St.Charles Consultancy, Winston Salem, NC, USA; (3) Eurofins Lancaster Labs, Winston Salem, NC, USA
    E-liquids are hygroscopic, non-aqueous liquids containing a small amount of water (~3-15%). When the pH of a non-aqueous liquid is measured using conventional methods and calibration buffers, the value can only be regarded as an "apparent pH". ...

    A robust method for evaluating the pH of e-liquids

    ST. CHARLES F.K.(1); MOLDOVEANU S.(2); SCOTT W.(2)
    (1) St. Charles Consultancy, Lewisville, NC, USA; (2) R.J. Reynolds Tobacco Co., Winston-Salem, NC, USA
    The measurement of pH is one of the simplest and most common analytical methods practiced in the laboratory. The pH-meter is calibrated using certified buffers, the electrode is placed in the solution, and if a reading is obtained, the value is used. In ...

    Effects of acetate and charcoal sector position in Hoffmann analytes of dual and triple filter cigarettes

    RUFENER C.; BENSE T.; RUNGA N.; TAROCO E.; BONILLA T.; UMPIERREZ E.
    Compañia Industrial de Tabacos Montepaz S.A., Montevideo, Uruguay
    It is known that activated charcoal has a good general efficiency in the adsorption of components of the vapour phase of cigarette mainstream smoke. Many studies have been published concerning the different factors involved in the filtration efficiency of ...

    The migration during storage, transfer to smoke, and filtration efficiency of nicotine, glycerin, and propylene glycol in cigarettes.

    ST. CHARLES F.K.(1); MOLDOVEANU S.C.(2); MILLS H.D.(2); ANDRESEN N.P.(2)
    (1) St.Charles Consultancy, Winston-Salem, NC, USA; (2) R.J. Reynolds Tobacco Co., Winston Salem, NC, USA
    This study evaluated the migration during storage, transfer to smoke and filtration of nicotine, glycerin and propylene glycol (PG) for cigarettes with cellulose acetate/triacetin filters. Filtration efficiency (FE) and smoke yields were studied for two ...
