    Demonstrating the consistency of nicotine delivery from an e-cigarette is a requirement per EU Tobacco Product Directive (TPD) 2, Article 20, 3(f) (The European Council and the Council of the European Union, 2014). The Directive states that e-cigarettes ...

    Exhaled aerosol properties in a room following use of electronic cigarettes and conventional cigarettes

    CAHOURS X.(1); MARTUZEVICIUS D.(2); PRASAUSKAS T.(2); SETYAN A.(3,4); O’CONNELL G.(5); JULIEN R.(1); WANG J.(3,4); COLARD S.(1)

    Use of electronic cigarettes (e-cigarettes) is rapidly increasing among smokers as an alternative to conventional tobacco cigarettes (CC). As e-cigarettes do not contain tobacco and do not require combustion, the mechanism of aerosol generation within an ...

    Potential impact of partial and total filter ventilation blocking on cigarette mainstream emissions during smoking

    COLARD S.; VERRON T.; JULIEN R.; CAHOURS X.
    SEITA-Imperial Tobacco, Fleury-les-Aubrais, France
    Cigarette mainstream smoke yields are broadly proportional to the quantity of tobacco burned during puffs. A mathematical model was developed to calculate this quantity during smoking, taking into account the tobacco burning rates during and between puffs ...

    Application of linear models to link cigarette yields delivered under ISO and intense regimes

    JULIEN R.; VERRON T.; CAHOURS X.; COLARD S.
    SEITA, Imperial Tobacco Group, Fleury-les-Aubrais, France
    Since it was first requested to measure and to report tar and nicotine in a limited number of countries, observation is made of an increasing trend for more testing and reporting requirements. From a single regime and two smoke yields, recent ...

    Do cigarette smoke yields from a single smoking regime fit with current regulatory objectives?

    COLARD S.(1); VERRON T.(2); JULIEN R.(2); PURKIS S.W.(1); CAHOURS X.(2)
    (1) Imperial Tobacco Limited, Bristol, U.K.; (2) SEITA, Imperial Tobacco Group, Fleury-les-Aubrais, France
    Many regulations worldwide require the reporting of tar, nicotine and carbon monoxide (TNCO) and set limits on their yields measured following the ISO smoking regime (ISO3308, 2012). The intention of FCTC Art. 9 is to characterise and monitor cigarettes, ...

    Prediction of smoke exposure from smoking time

    CAHOURS X.(1); COLARD S.(2); VERRON T.(1); JULIEN R.(1); PURKIS S.W.(2)
    (1) SEITA, Imperial Tobacco Group, Fleury-les-Aubrais, France; (2) Imperial Tobacco Limited, Bristol, U.K.
    We have recently shown that cigarette smoke yield (TNCO) depends linearly on the difference between the time of smouldering and the time of smoking using several machine smoking regimes (CORESTA 2012), with the filter ventilation open or blocked. It is ...

    (1) SEITA, Imperial Tobacco Group, Fleury-les-Aubrais, France; (2) Imperial Tobacco Limited, Bristol, UK
    We have recently shown that cigarette smoke yield (TNCO) depends linearly on the difference between the time of smouldering and the time of smoking using several machine smoking regimes (TSRC 2012), with the filter ventilation open or blocked. It is ...
