    Survey on cadmium concentration in flue-cured, burley and oriental tobacco (Nicotiana tabacum) leaves

    LUGON-MOULIN N.; MARTIN F.; KRAUSS M.R.; RAMEY P.B.; ROSSI L.
    Philip Morris Intl, R&D, c/o Philip Morris Products SA, Neuchâtel, Switzerland, Philip Morris Intl Mgt SA, Leaf Agronomy, Lausanne, Switzerland, Philip Morris Intl, R&D, Richmond, VA, USA,
    Cadmium (Cd) is classified as a known human carcinogen (Class 1) by the International Agency for Research on Cancer. It is one of the potential carcinogenic substances in tobacco products. Cadmium accumulation in crop plants such as tobacco (Nicotiana ...

    Reduction of tobacco specific nitrosamines in air-cured tobacco

    LI Qinglin; KRAUSS M.; COLASSACO D.; BOKELMAN G.; GADANI F.; ROSSI L.
    Philip Morris USA, Research Center, Richmond, VA, USA
    Antioxidants, such as phenolics, tocopherols and carotenoids in tobacco leaves, are known to interfere with oxidation processes through chain-breaking reactions or through scavenging of free radicals. The induction or up-regulation of these and other ...

    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 only ...

    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) were ...
  6. CORESTA Meeting, Smoke Science/Product Technology, Stratford-upon-Avon, 2005, SSPT 44

    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 compounds. ...

    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 ...
