    Investigation of the mechanical extraction properties of the raw materials of reconstituted tobacco sheet

    SUNG Yong-Joo; HAN Young-Lim; BAEK Shin; KIM Kun-Soo; RHEE Moon-Soo
    KT&G Research Institute, Daejeon, South Korea
    The various wastes produced by the tobacco industry such as stems, scraps, winnowers, dust, etc., have been transformed into a valuable material, called a reconstituted tobacco sheet (RECON). Especially, the stem is one of the most important...

    Evaluation of inactivity of free radicals in cigarette mainstream smoke by cigarette filters treated with various antioxidants

    PARK Jin-Won; KIM Soo-Ho; KIM Jong-Yeol; KIM Chung-Ryul; RHEE Moon-Soo
    KT&G Research Institute, Daejeon, South Korea
    Cigarette mainstream smoke is a complex mixture of approximately 4,000 chemical constituents. It is well known, for example, that the cigarette smoke can contain high concentrations of free radicals that may bind to DNA and could lead to damage of...

    Physical properties of carbons prepared from a coconut shell by steam activation and chemical activation and the influence of prepared activated carbon on the delivery of mainstream smoke

    KO Dong-Kyun; SHIN Chang-Ho; LEE Young-Tae; JANG Hang-Hyun; RHEE Moon-Soo
    KT&G Research Institute, Daejeon, South Korea
    Several activated carbons with different specific surface areas were prepared by steam and chemical activation of coconut shell. Products were characterized by BET (N2) at 77K, and probed to reveal a highly specific surface area of 1580 m2/g and pore...

    Comparison of pyrolysis pattern of different tobacco leaves by double-shot pyrolysis-GC/MSD method

    LEE Chang-Gook; LEE Jae-Gon; JANG Hee-Jin; KWON Young-Ju; LEE Jang-Mi; KWAG Jae-Jin; RHEE Moon-Soo
    KT&G Research Institute, Daejeon, South Korea
    Thermal pyrolytic behaviour of different types of tobacco leaves, such as flue-cured, Burley and oriental tobacco were investigated using double-shot pyrolysis-GC/MSD methods. Three grades of flue-cured tobacco and Burley tobacco, and three origins...

    Evaluation of the behaviour of the anion in RECON extract by various adsorbents

    HAN Young-Rim; SUNG Yong-Joo; BAEK Shin; KIM Kun-Soo; RHEE Moon-Soo
    KT&G Research Institute, Daejeon, South Korea
    The objective of this study is to evaluate the behaviour of anions in RECON extract by various adsorbents and several ion exchange resins using ion chromatography. The determination of ionic species in solution is a classical problem with a variety...

    The influence of triacetin contents on the physical properties of carbon dual filter and on the delivery of mainstream smoke

    KO Dong-Kyun; LIM Hee-Jin; SHIN Chang-Ho; LEE Young-Taeg; RHEE Moon-Soo
    KT&G Research Institute, Daejeon, South Korea
    In this study, we have investigated the influence of triacetin contents on the variation of physical properties of the filters, the characteristics of the activated carbon and the delivery amount of mainstream smoke. The hardness, pressure drop of...

    Pyrolysis study using tobacco matrix mimicking real tobacco constituents by pyrolyzer-GC/MSD method: application to the pyrolysis of cigarette ingredients

    LEE Chang-Gook; LEE Jae-Gon; BAEK Shin; JANG Hee-Jin; KWON Young-Ju; KWAG Jae-Jin; RHEE Moon-Soo
    KT&G Research Institute, Daejeon, South Korea
    Tobacco constituents, such as cellulose, lignin and pectin were blended with appropriate level to make matrix mimicking the real tobacco constituents of Burley and flue-cured tobacco. The pyrolysis products of these matrices were determined by GC (HP...

    Study on the direct introduction of solvent condensed mainstream smoke for trace elements analysis by inductively coupled plasma mass spectrometry with an octopole reaction cell

    CHO Sung-Eel; OH In-Hyeog; HWANG Keon-Joong; RHEE Moon-Soo
    KT&G Research Institute, Daejeon, South Korea
    In conventional element analysis, samples of various types are usually prepared or digested and then introduced as solutions to a plasma by a nebulizer. However sample digestion is a tedious, labor-intensive and time-consuming process, and there is a...
