    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 ...

    Real-time on-line characterisation of selected Hoffmann analytes in inhaled and exhaled cigarette smoke (Mouthspace) by photo ionisation time-of-flight mass spectrometry

    STREIBEL T.; SKLORZ M.; MITSCHKE S.; ADAM T.; ZIMMERMANN R.
    University of Augsburg, Analytical Chemistry, Institute of Physics, Augsburg, Germany
    Chemical composition of cigarette smoke has been extensively researched in the past mostly using off-line methods such as GC/MS or HPLC. Often the smoke was already aged and altered by the sampling/trapping when it was analyzed. It is known that many ...

    Application of laser ionization mass spectrometry for on-line characterization of organic compounds in main- and sidestream smoke

    ADAM T.; MITSCHKE S.; STREIBEL T.; McAUGHEY J.; BAKER R.R.; ZIMMERMANN R.
    University of Augsburg, Analytical Chemistry, Institute of Physics, Augsburg, Germany
    Tobacco smoke is a fast changing and extremely complex mixture containing thousands of compounds. Consequently, to account for the dynamic smoke composition analytical techniques exhibiting a very high time resolution are required. The measurement ...

    On-line real-time analysis of organic compounds in mainstream tobacco smoke: An optimised coupling between a commercial smoke machine and fast photo-ionisation time-of-flight mass spectrometry

    ZIMMERMANN R.; STREIBEL T.; MÜHLBERGER F.; ADAM T.; MITSCHKE S.; BAKER R.R.; GONIN M.; FUHRER K.; ROSE N.
    University of Augsburg, Analytical Chemistry, Institute of Physics, Augsburg, Germany
    Since the chemical properties of tobacco smoke are changing very rapidly during the smoking process, time-resolved analysis is required to better understand the chemistry of smoking. Puff-resolved analysis of tobacco smoke can be done by conventional off ...

    Discrimination of three tobacco types by application of Thermal Desorption/Photo Ionisation Time-of-Flight Mass Spectrometry as well as investigation of sidestream smoke using Single Photon Ionisation/Time-of-Flight Mass Spectrometry

    MITSCHKE S.; STREIBEL T.; ADAM T.; BAKER R.R.; McAUGHEY J.; ZIMMERMANN R.
    University of Augsburg, Analytical Chemistry, Institute of Physics, Augsburg, Germany
    Recently, Pyrolysis Single Photon Ionisation/Time-of-Flight Mass spectrometry (Py-SPI-TOFMS) has been applied to differentiate between three major tobacco types, Burley, Virginia, and Oriental, respectively. In doing so, tobacco samples have been ...
