摘要
离子迁移谱技术(IMS)是从上世纪70年代发展起来的一项痕量气态物质探测技术。基于该技术的离子迁移谱仪具有结构简单,检测速度快、可以工作在大气环境下等优点,在微型化便携式应用中有巨大的发展潜力。通过参考国内外相关文献,着重从离子源、高场非对称离子迁移谱技术(FAIMS)和离子捕获装置三个方面对微型化离子迁移谱仪的研究现状进行了分析和探讨,并对该领域未来的研究方向和发展趋势提出了一些看法。
Ion mobility spectroscopy （IMS） is a trace gas detection technology developed from the seventies ot last century. There are lots of advantages for IMS, such as simple structure, fast detection speed, atmospheric working environ： ment. It has great potential for development in the miniature and portable applications. By reference to relevant literature at home and abroad, the development of miniaturized instruments was described and analyzed, especially on new ion source, high field asymmetric ion mobility spectrometry （FAIMS） technology and new ion capture devices. Besides that, some remarks were made in the development trends and future research direction in this area.
