热裂解气质技术在卷烟工业中的应用

摘要

热裂解仪在有氧氛围下对卷烟进行热裂解，可较简单地实现对卷烟燃烧过程的模拟，同时可通过气相色谱－质谱联用仪对裂解产物进行在线分析。热裂解－气相色谱质谱联用技术（Py－GC－MS，）具有操作简便、快速、用量少、灵敏度高、分离度好、可重复性强等特点，在烟草研究领域中应用越来越广泛，成为烟草化学研究的重要方法。介绍了裂解－气相色谱质谱联用技术和装置，总结了近十年来其在烟草行业的应用研究，并对其发展方向和应用前景进行了展望。%Pyrolysis could simulate cigarette combustion process, meanwhile, the products were analyzed by GC-MS.Py-GC-MS has the ad-vantages of simple operation, fast, low consumption, high sensitivity, good separation degree, strong repeatability, etc., and is widely used in the field of tobacco research, and is an important method for the research of tobacco chemistry.Py-GC-MS technology and device were intro-duced, the application of Py-GC-MS in tobacco industry in recent ten years were summarized, the development direction and application pros-pect was forecasted.
