    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...

    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...

    Application of single-photon ionisation time-of-flight mass spectrometry (SPI-TOFMS) with an electron beam pumped excimer light source for the on-line detection of organic compounds in mainstream smoke

    ZIMMERMANN R.; MÜHLBERGER F.; WIESER J.; ULRICH A.
    University of Augsburg, Analytical Chemistry, Institute of Physics, Augsburg, Germany
    Single-photon ionisation (SPI) with vacuum-ultraviolet (VUV) light allows an efficient and soft ionisation of organic compounds yielding mass spectra with no or only few fragment peaks. Selectivity is provided via the ionisation potential (IP), as...

    Puff-by-puff resolved measurements of cigarette smoke by resonance-enhanced multi-photon ionization (REMPI) and single photon ionization (SPI) - time of flight mass spectrometry (TOFMS)

    MITSCHKE S.; ADAM T.; STREIBEL T.; BAKER R.R.; ZIMMERMANN R.
    University of Augsburg, Analytical Chemistry, Institute of Physics, Augsburg, Germany
    The application of soft photo-ionization mass spectrometry methods (PIMS) for cigarette mainstream smoke (MSS) analysis is demonstrated. Resonance-enhanced multi-photon ionization (REMPI) and vacuum ultra violet light single-photon ionization (SPI)...

    Puff-by-puff resolved tobacco smoke particulates analyzed by comprehensive two-dimensional gas chromatography time-of-flight mass spectrometry (GCxGC TOFMS)

    WELTHAGEN W.; MITSCHKE S.; ADAM T.; STREIBEL T.; ZIMMERMANN R.
    University of Augsburg, Analytical Chemistry, Institute of Physics, Augsburg, Germany
    The potential use of GCxGC TOFMS in the analysis of puff-by-puff resolved tobacco smoke particulate matter collected on Cambridge filters is discussed. GCxGC-TOFMS is a technique suited to study complex samples consisting out of thousands of...

    Pyrolysis single-photon ionisation time-of-flight mass spectrometry (Py-SPI-TOFMS) for the discrimination of three tobacco types

    STREIBEL T.; ADAM T.; MITSCHKE S.; FERGE T.; BAKER R.R.; ZIMMERMANN R.
    University of Augsburg, Analytical Chemistry, Institute of Physics, Augsburg, Germany
    Pyrolysis single photon ionisation/time-of-flight mass spectrometry (Py-SPI-TOFMS) has been applied to differentiate between three major tobacco types, viz Burley, Virginia, and Oriental, respectively. SPI is known as a soft ionisation technique that...

    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.,...
