    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...

    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...

    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...

    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...

    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;...
