    Chemistry Dept., College of Chemistry and Chemistry Engineering, Nanjing University, Nanjing, China
    Tobacco smoke contains more than 4000 individual components in vapour phase and particulate phase. Therefore it is difficult to selectively capture the target carcinogens such as nitrosamines among varied compounds. Tobacco specific nitrosamines (TSNA) ...

    The application of the composite porous materials to reduce the harmful compounds in mainstream smoke

    CAO Yi; YUE Ming Bo; YANG Jing; ZHUANG Tingting; ZHU Jianhua; GHOSH M.; VAN HEEMST J.; CUNNINGHAM F.
    Nanjing University, Key Laboratory of Mesoscopic Chemistry of MOE, School of Chemistry and Chemical Engineering, Nanjing, China.
    In order to reduce the harmful compounds in cigarette smoke, two types of composite porous materials are synthesized. Based on mesoporous materials, SBA-15 and MCM-41, zeolites HZSM-5 and NaY fragments are introduced into the synthetic system and ...

    Nanjing University, School of Chemistry and Chemical Engineering, Nanjing, China.
    Capturing the carcinogenic constituents such as volatile nitrosamines in tobacco smoke is a challenge not only for the tobacco industry to reduce the harm of smoking, but also for the chemist to prepare novel selective adsorbent, because it is hard to ...

    Feature selection from near infrared spectra using genetic algorithms for tobacco blend recognition

    FIGUERES G.; DE SOUZA S.; REYNES C.; SABATIER R.; VIDAL B.
    Altadis Research Centre, Fleury-les-Aubrais, France
    Near infrared reflectance spectroscopy has proved to be very useful for predicting concentrations of chemical compounds in tobacco, classification or pattern recognition of cigarette blends. The resulting measurement of a sample is a whole reflectance ...

    How representative of the human smoking behaviour would be the new alternative smoking regimes? A first attempt of assessment

    MARCHAND V.; TESSIER C.; DUMERY B.
    Altadis Research Centre, Fleury-les-Aubrais, France
    The ISO or FTC smoking conditions (35 mL- 2 s puffs, 1 puff per minute) have been more and more criticized during the last decade, especially because they would not reflect the human smoking behaviour. Their main objective was not to predict the exact ...

    A mixture experimental design with six variables and the effects on smoke components:1 - Presentation of this experimental design and of some initial results on physical characteristics of cigarettes and blends

    VIDAL B.; FIGUERES G.; BIESSE J.P.; BREGEON B.; LOUVET F.; MUZELLEC L.
    Altadis Research Centre, Fleury-les-Aubrais, France
    The objective of this paper is to examine the effects of six tobacco components on the chemical and physical characteristics of blends and cigarettes and particularly on the mainstream smoke yields. First of all, we will develop the philosophy of this ...
