    (1) SEITA, Imperial Tobacco Group, Fleury-les-Aubrais, France; (2) Imperial Tobacco Limited, Bristol, UK
    LIP cigarette paper is usually a standard cigarette paper on which zones with starch or another material with reduced air permeability have been printed equidistantly. The porosity of the LIP zones (reduced porosity zones) is designed so that the ...

    Analytical method validation – application of the accuracy profile to the method “determination of total alkaloids in tobacco”

    TEILLET B.(1); VERRON T.(1); CAHOURS X.(1); COLARD S.(2)
    (1) SEITA, Imperial Tobacco Group, Fleury-les-Aubrais, France; (2) Imperial Tobacco Limited, Bristol, UK
    In the context of methodology for cigarette product characterisation, it is important to subject the method to its intended-use (e.g. regulatory requirement) in order to confirm its “fitness for purpose” as described in ISO17025. The objective is to ...

    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 ...

    Trend analysis: a relevant tool to assess post-regulation impacts

    VERRON T.(1); CAHOURS X.(1); COLARD S.(2)
    (1) SEITA, Imperial Tobacco Group, Fleury-les-Aubrais, France; (2) Imperial Tobacco Limited, Bristol, UK
    After the implementation of a new regulation, which imposes some changes on products or consumer behaviours, it is important to know if the impact is in line with the expectations or not. To assess this impact the best method is to compare the figures ...

    Investigation of tobacco precursors on the formation of smoke acetaldehyde: sugars, sucrose esters and sugars from cellulose

    TEILLET B.(1); CAHOURS X.(1); VERRON T.(1); COLARD S.(2)
    (1) SEITA, Imperial Tobacco Group, Fleury-les-Aubrais, France; (2) Imperial Tobacco Limited, Bristol, UK
    The generation of smoke acetaldehyde has been cited as being linked to the combustion of carbohydrates, particularly sugars and cellulose on the basis of pyrolysis experiments or cellulose made cigarettes [1]. In this study, the effects of tobacco free ...

    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; ...

    THEME-SEER: Multidimensional exploratory technique to explore the generation process of smoke compounds

    BRY X.(1); VERRON T.(2); CAHOURS X.(2); TEILLET B.(2)
    (1) I3M, UM2, Montpellier, France; (2) SEITA, Imperial Tobacco Group, Fleury-les-Aubrais, France
    In 2011, we presented at the 2011 CORESTA SSPT Meeting (Graz) [1] a new approach to path modelling based on system extended multiple covariance criteria. We showed why THEME-SEER may be preferred to current methods using either criteria based on ...

    Limitation of standard deviation to express variability.

    TEILLET B.(1); VERRON T.(1); CAHOURS X.(1); COLARD S.(2); PURKIS S.(2)
    (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 ...
