    (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...

    There are regulatory requirements in quantifying and comparing the emission levels of major and minor aerosol constituents from e-cigarettes. Up until the recent publication in 2015 of CORESTA Recommended Method (CRM) No. 81 - "Routine Analytical...
  6. CORESTA Meeting, Smoke Science/Product Technology, 2017, Kitzbühel, ST 44

    Investigation of tetrahydrocannabinol (THC) in smoke by application of an online photo ionisation mass spectrometry

    Implications of product testing: method variability and suitability and ratio of smoke emissions to nicotine

    INTORP M.
    (1) Reemtsma Cigarettenfabriken GmbH (an Imperial Brands PLC Company), Hamburg, Germany; (2) SEITA-Imperial Tobacco, Fleury-les-Aubrais, France
    Regulatory authorities are discussing the measurement of certain smoke constituents, and this may eventually lead to discussion of ceilings. For this purpose internationally standardised methods are required to enable the generation of reliable data....
