    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 ...

    The prevention of TSWV attack in the Burley fields in Romania

    STANESCU V.; PAUNESCU A.D.; DIMA A.; PAUNESCU M.; BURCEA A.M.; SANISLAV N.
    Central Research Station for Tobacco Culture and Industrialization, Bucharest, Romania.
    The Burley cultivars are very sensitive to virosis, in general, and to TSWV, in particular.Yield and quality of the obtained tobacco largely depend on the prevention of this virus, and this is managed by the chemical control of Thrips tabaci Lind., the ...
