Growing concern about the effects of atmospheric pollutants on climate and human health has accelerated the development of novel analytical methods, including sampling systems, for the determination of atmospheric volatile organic compounds (VOCs). Miniaturised air sampling (MAS) techniques have attracted wide attention in the past two decades due to their advantages (ease of operation, time-integrated sampling, small/no organic solvent consumption, and potential for automation). This review focuses on the latest developments in these techniques, including needle trap microextraction (NTME), in-tube extraction (ITEX), sorption trap, solid-phase microextraction (SPME fibre, SPME Arrow, and retracted SPME fibre), thin-film microextraction (TFME), solid-phase dynamic extraction (SPDE), and stir bar sorptive extraction (SBSE). Further, their benefits, drawbacks, and applicability to air sampling are discussed. The applications of MAS techniques for the analysis of atmospheric air, indoor air, breath air, and emissions of plants and foods are summarised and discussed.

微型空气采样技术,用于分析空气中的挥发性有机化合物

人们越来越关注大气污染物对气候和人类健康的影响,从而加快了包括采样系统在内的测定大气中挥发性有机化合物(VOC)的新型分析方法的开发。微型空气采样(MAS)技术由于其优点(操作简便,时间积分采样,有机溶剂消耗少/无,并且具有自动化的潜力)在过去的二十年中受到了广泛的关注。这篇综述重点关注这些技术的最新发展,包括针阱微萃取(NTME),管内萃取(ITEX),吸附阱,固相微萃取(SPME纤维,SPME Arrow和缩回的SPME纤维),薄膜微萃取(TFME),固相动态萃取(SPDE)和搅拌棒吸附萃取(SBSE)。此外,它们的好处 的缺点,并适用于空气采样。总结并讨论了MAS技术在分析大气,室内空气,呼吸空气以及植物和食物排放中的应用。
