    Optimized analytical method of hydrogen cyanide in mainstream smoke using continuous flow analyzer

    NA Seung-Ju; BOCK Jin-Young; HWANG Keon-Joong
    KT&G Research Institute, Daejeon, South Korea
    Hydrogen cyanide (HCN) is present in both the particulate phase and vapour phase of cigarette smoke. It is one of the 44 harmful substances on the Hoffmann list and is known to be a major ciliatoxic agent in cigarette smoke. Typically the...

    Semi-quantitative analysis of cigarette by inductively coupled plasma mass spectrometry

    CHO Sung-Eel; KIM Hyo-Keun; HWANG Keon-Joong
    KT&G Research Institute, Daejeon, South Korea
    Inductively coupled plasma mass spectrometry (ICP-MS) has become a popular technique in multi-element analysis since the first commercial instrument became available in 1980s. Semi-quantitative analysis by ICP-MS has proven to be a powerful tool for...

    The determination of multiple agrochemical residues in tobacco by gas chromatography-triple quadrupole mass spectrometry

    LEE Jeong-Min; JANG Gi-Chul; HWANG Keon-Joong
    KT&G Research Institute, Daejeon, South Korea
    Traditionally agrochemical residues in tobacco have been analyzed with multi-residue methods by using gas chromatography with either selective detectors (ECD, NPD, FPD) or mass spectrometry. Because many modern agrochemicals are either not amenable...

    Analysis of acrylamide in mainstream cigarette smoke and effects of reducing sugars on acrylamide content

    KIM Ick-Joong; LEE John-Tae; MIN Hye-Jeong; KIM Hyo-Keun; HWANG Keon-Joong
    KT&G Research Institute, Daejeon, South Korea
    Acrylamide has been found in many foods in our everyday life. Acrylamide levels in foodstuffs were analyzed by a GC/MS after bromination of acrylamide and by a LC/MS for underivatized acylamide. In these methods, various clean up procedures are...

    Characteristic of analytical techniques for hydrogen cyanide in mainstream smoke

    LEE John-Tae; KIM Hyo-Keun; HWANG Keon-Joong; LEE Kyung-Gu; JANG Seok-Su
    KT&G Research Institute, Daejeon, South Korea
    Hydrogen cyanide (HCN), formed from pyrolysis of various nitrogenous compounds such as protein, amino acids and nitrate in tobacco, is present in both the particulate phase and vapor phase of cigarette smoke. Typically the determination of HCN in...

    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...
