    Comparison of two different high-resolution mass spectrometers for untargeted LC/MS analysis of cigarette smoke extracts

    TAKANAMI Y.; KITAMURA N.; ORIKATA N.; TOBITA T.
    Japan Tobacco Inc., Yokohama, Kanagawa, Japan
    Cigarette smoke contains at least 6000 compounds. Comprehensive chemical analysis of this complex mixture is often achieved by untargeted liquid chromatography (LC)/mass spectrometry (MS) analysis, which requires the use of several state-of-art ...

    Comparison of hydrophilic interaction liquid chromatography and reversed-phase separation in untargeted LC/MS analysis of 3D cell cultures exposed to cigarette smoke and aerosols from a novel tobacco vapor product

    TAKANAMI Y.; KITAMURA N.; ITO S.
    Japan Tobacco Inc., Yokohama, Japan
    Aerosols from a novel tobacco vapor product (NTV) generate lower levels of potentially harmful constituents than cigarettes. In vitro cell cultures are expected to exhibit early-phase biological responses to cigarette smoke; a comprehensive analysis of ...
