摘　　要：建立了全二维气相色谱-飞行时间质谱(GC×GC-TOF MS)分析卷烟主流烟气中中性化学成分的方法。以较长的弱极性柱HP-5MS(50 m×0.2 mm i.d.×0.33μm)作为第一维柱,较短的薄液膜中等极性柱DB-17MS(1.7 m×0.1 mm i.d.×0.1μm)作为第二维柱,对优质烟叶单料卷烟烟气的中性成分进行定性分析,经过人工纠错等分析初步鉴定出匹配度大于700的1 464种成分,重点讨论了中性香味羰基化合物全二维点阵的谱图特征,为烟气和复杂体系的深入研究提供了方法学基础。Neutral fraction of cigarette particulate matter was investigated by comprehensive two-di- mensional gas chromatography coupled with time of flight mass spectrometric （ GC × GC - TOF MS） method. An HP-5MS（50 m ×0.2 mmi. d. x0. 33 μm） column was chosen as the first dimensional column and a DB-17MS（ 1.7 m ×0. 1 mm i. d. ×0. 1 μm） as the second dimensional column to sepa- rate and analyze the neutral constituents of smoke particulate matter of high-quality tobacco. Total of 1 464 compounds were tentatively identified by TOF MS software based on auto data processing com- bined with manual data processing. The structured related compounds such as ketones and aldehydes eluted in bands or clusters in the GC x GC chromatograph were investigated. The retention time for 36 flavor constituents in the first dimension and second dimension were discussed, and the characteristics of the aldehydes in the comprehensive two-dimensional gas chromatography were studied. The infor- mation and the interpretations of spectra characteristics will enhance＇the reliability of compound identi- fication and be helpful in the study of tobacco smoke and other complex system.
