    Analysis of N-nitrosodimethylamine in smokeless tobacco by use of UHPLC-MS/MS

    ERICSSON D.; PATRING J.; KALVO D.; LINDHOLM J.
    Swedish Match North Europe AB, Stockholm, Sweden
    N-nitrosodimethylamine (NDMA) is a member of the compound group N-nitrosamines and is a carcinogenic substance belonging to IARC Group 2A. In addition, NDMA is on the FDA "Established List for Harmful and Potentially Harmful Constituents in Tobacco ...

    Analysis of coumarin in tobacco and smokeless tobacco by use of UHPLC-MS/MS

    PATRING J.; KALVO D.; ERICSSON D.; LINDHOLM J.
    Swedish Match North Europe AB, Stockholm, Sweden
    The demand for chemical analysis is increasing; the number of routine assays is steadily increasing as well as requests for new assays required by the regulators. Coumarin is one of the constituents of regulatory concern on FDA’s established list for ...

    Analysis of volatile aldehydes in smokeless tobacco with a rapid, one-step extraction and derivatisation with UHPLC-MS/MS quantification

    ERICSSON D.; PATRING J.; LINDHOLM J.
    Swedish Match North Europe AB, Stockholm, Sweden
    The volatile carbonyls formaldehyde, acetaldehyde and crotonaldehyde have routinely been analysed in tobacco smoke for many years, but much lesser in smokeless tobacco. Since 2012 they have been included in the “Draft Proposed Initial List of Harmful ...

    A more accurate estimation of free-base nicotine in moist snuff

    STAAF M.; HODIN F.; LUNDIN J.
    Swedish Match North Europe AB, Research & Development, Stockholm, Sweden
    The term “free-base” nicotine (FBN) refers to the unprotonated or un-ionised form of nicotine which is readily available for uptake through the mucous membrane. Commonly, the availability of FBN in moist snuff is estimated by the Henderson-Hasselbalch ...

    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 ...

    A mixture experimental design with 6 variables and the effects on smoke components:2 - Hoffmann analytes behaviour through a mixture experimental design

    FIGUERES G.; VIDAL B.; BIESSE J.P.; BREGEON B.; LOUVET F.; MUZELLEC L.
    Altadis Research Centre, Fleury-les-Aubrais, France
    Today in the tobacco industry, one of the main scientific challenges is to understand the formation of some smoke compounds ("Hoffmann analytes"). For several years, work has been conducted in order to know the influence of cigarette design ...
