    Fast on-line tobacco smoke analysis with Photo Ionisation - Time-of-Flight-Mass Spectrometry - Part 1: Scientific background and basic principles

    ZIMMERMANN R.; MÜHLBERGER F.; MITSCHKE S.; STREIBEL T.; ROSE N.
    University of Augsburg, Analytical Chemistry, Institute of Physics, Augsburg, Germany
    Mass spectrometry (MS) with soft ionisation (i.e. non fragmenting ionisation) allows a direct on-line monitoring of organic compounds in complex gaseous matrices such as tobacco smoke. Photo ionisation (PI) methods are particularly well suited for...

    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...

    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...
