  1. CORESTA Meeting, Smoke Science/Product Technology, 2019, Hamburg, STPOST 18 (also presented at TSRC 2019)

    Comparison of a flame ionization detector (GC/FID) to a nitrogen-phosphorus detector (GC/NPD) for gas chromatographic determination of nicotine in conventional and ultra-low nicotine tobacco blends

    STINSON A.; STEELMAN D.; CLARK T.J.
    Liggett Group LLC, 100 Maple Lane Mebane NC, U.S.A.
    The established CORESTA method to determine nicotine in tobacco uses a gas chromatograph coupled with a flame ionization detector (GC/FID) (CRM 62) that uses mass spectrometry (GC/MS) (CRM 87). These methods were developed to evaluate conventional tobacco ...

    University of Alicante, Alicante, Spain
    Certain mesoporous materials can modify notably the composition of smoke tobacco, since they can act as catalysts and/or adsorbents allowing to reduce the toxic and carcinogenic compounds of the smoke. However, the properties of the catalysts strongly ...

    Effect of SBA-15 morphology in the composition of the mainstream tobacco smoke

    MARTÍNEZ-CASTELLANOS I.; MARCILLA A.; BELTRÁN M.I.; BERENGUER D.; BLASCO I.; JUAREZ N.; ASENSIO J.; CALABUIG E.
    University of Alicante, Alicante, Spain
    Mesoporous silica materials, such as SBA-15, are attracting increasing interest in the last years. Our research group has focused in their capability for reducing the toxic compounds generated in the smoking process when mixed with tobacco. By tuning the ...

    Effect of the addition of SBA-15 in the pyrolysis of a reference tobacco under inert and oxidizing atmosphere

    CALABUIG E.; MARCILLA A.; BELTRÁN M.I.
    University of Alicante, San Vicente del Raspeig, Spain
    The composition of evolved products from slow pyrolysis under inert and oxidizing atmospheres of a reference tobacco 3R4F from the Reference Cigarette Program of the College of Agriculture of the University of Kentucky and a mixture of the reference ...

    Influence of the time of synthesis of SBA-15 on its effect as a catalyst reducing toxicant concentration in tobacco smoke

    JUÁREZ-SERRANO N.; MARCILLA A.; BELTRÁN M.I.
    University of Alicante, San Vicente del Raspeig, Spain
    In recent years, SBA-15 has been suggested as an additive for reduction of toxic compounds in tobacco smoke. The structure of this type of materials is strongly dependent on the synthesis conditions. The objective of the present work is to analyze the ...
