    Determination of tobacco-specific N-nitrosamines (TSNAs) in mainstream cigarette smoke by heart-cutting two dimensional liquid chromatography–tandem mass spectrometry (2DLC-MS/MS)

    CHEN Min; WANG Leijun; QI Dawei; LIU Baizhan; WU Da
    Shanghai Tobacco Group Co., Ltd., Technology R&D Center, Shanghai, P.R. China
    Accurate results are often hard to obtain in the determination of tobacco-specific N-nitrosamines (TSNAs) in mainstream smoke of Virginia type cigarette due to the low deliveries of TSNAs and the complicated matrix disturbance; therefore, a novel...
