    Identification and quantification of free radical content in cigarette smoke using nanoLC nano ESI FT-ICR MS/MS

    LE FAOUDER P.; TOKARSKI C.; EMAMI I.; ROLANDO C.
    University of Sciences and Technologies of Lille, Laboratory of Organic and Macromolecular Chemistry, CNRS IMR 8009, Villeneuve d'Ascq, France
    Cigarette smoke is a highly complex aerosol of several thousand chemical substances of which free radicals, short-life time molecules, are present in high concentration. In order to identify and quantify them, we have developed a new methodology...

    Removal of free radicals in mainstream cigarette smoke by filters including natural antioxidant: identification and behavior of oxygen, nitrogen and carbon centered radicals by a new and robust LC-MS/MS method

    ROLANDO C.; EMAMI I.; MASSELOT D.; LE GAC S.
    Université des Sciences et technologies de Lille, UMR CNRS 8009, Villeneuve d'Ascq cedex, France
    The presence of free radicals in cigarette smoke was demonstrated more than 40 years ago by freezing of mainstream smoke and analyzing the resulting solid using ESR techniques1. Free radicals play a central role in ageing diseases like cancer,...
