烟草挥发性有机物的高效采样分析技术研究进展

烟草挥发性有机物(Volatile organic compounds,VOCs)含量低、组成复杂、挥发性强，同时烟草及其产品基体极其复杂，发展烟草VOCs的高效采样分析技术具有重要意义。该文综述了近年来烟草VOCs分离富集介质(如石墨烯及其复合材料、硅基材料、磁性富集材料等)及相关采样技术(如QuEChERS技术、固相微萃取技术、液相微萃取技术等)的研究进展，总结了烟草VOCs分析技术在烟草产品质量控制等方面的实际应用情况，并展望了该领域的未来研究趋势。

Research Progress of Efficient Sampling and Analytical Techniques for Tobacco Volatile Organic Compounds

It''s of great significance to develop efficient sampling and analytical techniques for tobacco volatile organic compounds(VOCs) as the tobacco VOCs from complicated tobacco matrix are usually at low content with complex composition and high volatility.The recent progresses on the separation or enrichment media such as graphene composite material,silicon-based material,and magnetic extraction sorbent,etc.,as well as related sampling techniques for tobacco VOCs,including QuEChERS,solid phase microextraction and liquid phase microextraction,etc.,are reviewed in this paper.Meanwhile,the corresponding applications of analytical techniques for tobacco VOCs in terms of quality control,etc.are also summarized.Finally,the future research trend of this field is prospected in this paper.
