    Identifying suitable biomarkers of biological effects (BOBEs) for evaluating reduced risk products

    SCHERER G.; PLUYM N.; SCHERER M.
    ABF Analytisch-Biologisches Forschungslabor GmbH, Planegg, Germany
    Switching from conventional cigarettes (CCs) to reduced risk products (RRPs), such as e cigarettes, heat-not-burn and oral tobacco products, could be an effective approach for tobacco harm reduction (THR), provided that the use of RRPs effectively entails ...

    Puff resolved determination of selected constituents in the aerosol of commercially available tobacco heating products using photoionisation mass spectrometry

    EHLERT S.(1,2); HEIDE J.(2); WALTE A.(1); ZIMMERMANN R.(2)
    (1) Photonion GmbH, Schwerin, Germany; (2) University of Rostock, Dept. of Analytical Chemistry, Rostock, Germany
    Commercially available tobacco heating products (THPs) are somehow hybrids between conventional cigarettes and e-cigarettes, as tobacco material is not burnt, but heated. Although the first THPs were coal heated and launched decades ago, currently ...

    On-line puff resolved analysis of cigarette smoke, e-cigarette vapour and vapour of tobacco heating products

    ZIMMERMANN R.(1); EHLERT S.(1,2); HEIDE J.(1); WALTE A.(2)
    (1) University of Rostock, Dept. of Analytical Chemistry, Rostock, Germany; (2) Photonion GmbH, Schwerin, Germany
    Photo ionisation-time of flight mass spectrometry (PI-TOFMS) has been established for on-line analysis of complex gas mixtures. Cigarette smoke, e cigarette vapour and the vapour of tobacco heating products provide good examples for such complex gas ...

    Novel biomarkers to characterize exposure to aldehydes from e-vapor products based on stable-isotope constituents

    LANDMESSER A.(1); SCHERER M.(1); SCHERER G.(1); SARKAR M.(2); EDMISTON J.S.(2); PLUYM N.(1)
    (1) ABF Analytisch-Biologisches Forschungslabor GmbH, Planegg, Germany; (2) Altria Client Services LLC, Center for Research and Technology, Richmond, VA, U.S.A.
    E vapor products (EVP) are an emerging category of non-combustible tobacco products that hold the promise of harm reduction for users of combustible products. Degradation products such as aldehydes have received much attention lately, however human ...

    Analytical methods for the determination of aldehydes in e-vapor aerosol and cigarette smoke and their urinary biomarkers of exposure

    LANDMESSER A.(1); SCHERER M.(1); SCHERER G.(1); SARKAR M.(2); EDMISTON J.S.(2); PLUYM N.(1)
    (1) ABF Analytisch-Biologisches Forschungslabor GmbH, Planegg, Germany; (2) Altria Client Services, Center for Research and Technology, Richmond, VA, U.S.A.
    Potential exposure to aldehydes, such as acrolein, formaldehyde or acetaldehyde, formed due to thermal degradation of the e-liquid constituents propylene glycol (PG) and glycerol (G) during the consumption of e-vapor products (EVPs), have received much ...
