    Investigation of tobacco pyrolysis gases and puff-by-puff resolved cigarette smoke by single photon ionisation (SPI) - Time-of-flight Mass Spectrometry (TOFMS)

    ADAM T.; MITSCHKE S.; BAKER R.R
    University of Augsburg, Analytical Chemistry, Institute of Physics, Augsburg, Germany
    The work presented deals with the application of Single Photon Ionisation- Time-of-Flight Mass Spectrometry (SPI-TOFMS) for the investigation of tobacco smoke. SPI-TOFMS is a modern analytical technique, which enables the simultaneous analysis of a large ...

    A robust method for estimating human smoked cigarette yields from filter analysis data

    ST. CHARLES F.K.; ASHLEY M.; SHEPPERD C.J.
    Consultant, 2250 Hilltop Dr, Winston-Salem, NC 21706, USA
    The analysis of spent filters from human-smoked (HS) cigarettes has been used to estimate cigarette yields for over three decades. Until recently, the whole filter was used for estimation; however a part-filter method has been shown to improve the ...

    The effect of fertilization and mycorrhiza on cadmium uptake by tobacco

    JANOUSKOVA M.; LUGON-MOULIN N.; MARTIN F.
    Institute of Botany, Academy of Sciences of the Czech Republic, Dept. of Mycorrhizal Symbioses, Prùhonice, Czech Republic.
    The effect of fertilization and arbuscular mycorrhiza (AM) on cadmium (Cd) uptake by tobacco (Nicotiana tabacum L.) was studied in a greenhouse pot experiment. Two tobacco varieties and five AM fungal isolates were included in this study. Each combination ...

    The chemical components identified in tobacco and tobacco smoke prior to 1954: a chronology of classical chemistry

    RODGMAN A.; PERFETTI T.A.
    Alan RODGMAN, 2828 Birchwood Drive, Winston-Salem, North Carolina, 27103-3410, USA
    Because of the excellent fractionation and identification technologies developed during the early-1950s, the compositions of tobacco and tobacco smoke, both classified as highly complex mixtures, have been defined more completely than the composition of ...

    Monitoring the bacterial and fungal biota of eleven tobacco grades stored at three different locations

    VILLEMUR R.; LACASSE M.; MORIN A.
    2900 Beaudoin, Montreal, QC, H4K 2R5, Canada
    Tobacco as many other plants has its own microbiota. There are very few studies determining the evolution of this microbiota during tobacco storage, which may affect the quality of tobacco. Polymerase chain reaction (PCR) combined with denaturing gradient ...

    The influence of a humectant on the retention by humans of solanesol from cigarette smoke. (Part 2. Glycerin)

    MOLDOVEANU S.C.; COLEMAN W.M.III
    R.J. Reynolds Tobacco Company, R&D, Winston-Salem, NC, USA
    Two common humectants are used as additives in the cigarette manufacturing process, propylene glycol (PG) and glycerin. The humectants may influence the deposition of cigarette smoke in the human respiratory tract by affecting the hygroscopic properties ...

    The composition of cigarette smoke. An historical perspective of several polycyclic aromatic hydrocarbons

    RODGMAN A.; COOK L.C.
    Alan RODGMAN, 2828 Birchwood Drive, Winston-Salem, North Carolina, 27103-3410, USA
    Because of the significant advancements in fractionation, analytical, and characterization technologies since the early 1960s, hundreds of components of complex mixtures have been accurately characterized without the necessity of actually isolating the ...
