    Challenges on HPHC analysis – the limit of quantification

    TEILLET B.(1); VERRON T.(1); CAHOURS X.(1); COLARD S.(2); PURKIS S.(2)
    (1) Imperial Tobacco Group, SEITA, Fleury-les-Aubrais, France; (2) Imperial Tobacco Ltd, Bristol, U.K.
    In the framework of growing regulations regarding tobacco products, increasing requirements for reporting of analytical figures are observed (e.g. FDA Draft guidance for Reporting Harmful and Potentially Harmful Constituents (HPHC) in Tobacco Products and ...

    Comparison of analytical data provided by different laboratories

    CAHOURS X.(1); VERRON T.(1); PURKIS S.(2); COLARD S.(2)
    (1) SEITA, Imperial Tobacco Group, Fleury-les-Aubrais, France; (2) Imperial Tobacco Limited, Bristol, UK
    Regulatory authorities are currently discussing the measurement and imposition of ceilings on certain smoke constituents. However, if routine measurement of these constituents is to be required, the laboratories need to use the same validated methods and ...

    Cigarette burning and alternative smoking regime

    COLARD S.(1); VERRON T.(2); PURKIS S.(1); CAHOURS X.(2)
    (1) Imperial Tobacco Limited, Bristol, UK; (2) SEITA, Imperial Tobacco Group, Fleury-les-Aubrais, France
    The combustion of a cigarette during smoking can be described as successive steps of active (during the puff) and passive (smouldering) burning from which a simple modelling approach can be derived. A sequential cigarette burning model has been developed ...

    Product compliance mapping

    CAHOURS X.(1); VERRON T.(1); PURKIS S.(2); COLARD S.(2)
    (1) SEITA, Imperial Tobacco Group, Fleury-les-Aubrais, France; (2) Imperial Tobacco Limited, Bristol, UK
    The joint working group of the WHO Study group on Tobacco Product Regulation (TobReg) have recommended a list of selected toxicants for regulation: N’-nitrosonornicotine (NNN); 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK); acetaldehyde; acrolein; ...

    (1) SEITA Imperial Tobacco Group, Fleury-les-Aubrais, France; (2) Imperial Tobacco Limited, Bristol, UK
    In the framework of growing regulations regarding tobacco products, increased requirements are observed for reporting of analytical figures (e.g. FDA). This paper deals with the reporting of data variability in this context. The objective was to evaluate ...

    Further investigations of temperatures and adsorption/desorption of volatile compounds in carbon filters under different smoking regimes

    TEILLET B.; PURKIS S.; CAHOURS X.
    Imperial Tobacco Group, Seita Research Centre, Fleury-les-Aubrais, France
    Previous work on "7 mg ISO tar" cigarettes containing an activated carbon filter had shown a significant removal of volatiles in mainstream smoke under ISO smoking. Our work had also shown that high filter temperatures associated with the ...

    Investigation of filter temperatures and desorption of volatiles from carbon filters under different smoking regimes

    TEILLET B.; MÜLLER C.; CAHOURS X.; PURKIS S.
    Imperial Tobacco Group, Seita Research Centre, Fleury-les-Aubrais, France
    There is a current regulatory interest in smoke yields obtained under both ISO and more intense smoking regimes and the relative advantages or disadvantages of using each regime. Smoke temperatures in filters of 1-mg and 13-mg ISO "tar" products ...
