    Non-targeted chemical characterization of complex matrices by nominal- and high-resolution accurate-mass GC×GC–TOFMS

    ALMSTETTER M.; KNORR A.; RHOUMA M.; MARTIN E.; CASTELLON A.; POSPISIL P.; BENTLEY M.; GOUJON C.
    Philip Morris Products S.A., PMI R&D, Neuchâtel, Switzerland
    Comprehensive chemical characterization is an important element in the development of heat-not-burn products. Beyond the challenge of developing powerful analytical methods with sufficient chromatographic and spectral resolution, it is essential to...

    Untargeted chemical characterization of the aerosol generated by a heated tobacco product

    BENTLEY M.; ALMSTETTER M.; ARNDT D.; KNORR A.; MARTIN E.; POSPISIL P.; MAEDER S.
    Philip Morris Products S.A., PMI R&D, Neuchâtel, Switzerland
    In contrast to quantitative analysis, where chemical constituents of interest are targeted to the exclusion of all others, an untargeted approach considers indiscriminate determination of all analytes relevant to a specific chemical space. A...

    Dos and don’ts in the design of indoor air quality studies on smoke-free products

    MITOVA M.I.; GOUJON-GINGLINGER C.; GOMEZ LUESO M.; ROTACH M.; MAEDER S.
    Philip Morris Products S.A., PMI R&D, Neuchâtel, Switzerland
    Indoor air quality (IAQ) studies on smoke-free products (SFPs), such as electrically heated tobacco products (EHTPs) and e-vapour products (EVPs), have demonstrated substantial reduction of environmental emissions relative to cigarette smoking. IAQ...

    Metabolic and transcriptomic shifts during tobacco leaf post-harvest senescence

    BOVET L.; HILFIKER A.; BATTEY J.; SIERRO N.; GOEPFERT S.
    PMI R&D, Philip Morris Products S.A., Neuchâtel, Switzerland
    Tobacco is harvested after plant flowering, when the leaf senescence is more or less visible depending on cultivars. Before the drying phase, current practices allow the senescence to proceed until the detached leaf becomes yellow. This yellowing...
