    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;...

    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...

    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...

    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 characterization, 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 and ASTM E2857-11....

    Cigarette burning and alternative smoking regime

    COLARD S.(1); VERRON T. (2); PURKIS S.W.(1); CAHOURS X.(2)
    (1) Imperial Tobacco Limited, Bristol, UK; (2) SEITA, Imperial Tobacco Group, Fleury-les-Aubrais, France
    Context and objective: Some regulations require the use of two smoking regimes. The objective of this study is to better understand the impact of the smoking regime on the cigarette burning process. The combustion of a cigarette during smoking can be...
