摘　　要： 电感耦合等离子体质谱技术(ICP-MS)是一种有效用于元素检测的现代分析方法。文中简述了ICP-MS和流动注射分析法(FI)的基本原理;FI做为一种样品引入方式和多功能的在线样品处理手段以其特有的优点越来越广泛的在ICP-MS分析中得到应用。FI使ICP-MS对高盐溶液承受力提高,使在小稀释因数下将样品溶液引入ICP-MS成为可能,从而可以降低检出限;FI-ICP-MS对有机溶剂有较高的承受力解决了ICP-MS分析含有机物质溶液时的一些问题。本文综述了FI-ICP-MS联用技术在分析环境、生物样品、药品、食品等样品中的研究进展以及微流动注射、芯片纳流动注射和等离子体质谱的联用进展。并指出随着我国国力的增强,经济的发展将会使ICP-MS越来越普及,FI-ICP-MS的联用技术研究越来越受到关注,其应用范围也将会大大拓宽。 Inductively coupled plasma mass spectrometry (ICP-MS) is one of the modern analytical methods for the detection of elements. In this paper, the basic principles of ICP-MS and flow injection (FI) were introduced. As a sample injection method and on-line sample treatment method, FI is widely combined with ICP-MS analysis with its unique merit. Combined with FI, the enduring capacity of ICP-MS to high salt solution is improved and decreases the detection limit, which makes it possible for the injection of samples into ICP-MS with small dilution factor. At the same time, the high enduring capacity of FI-ICP-MS to organic solvent can resolve the problems caused by the organic material solution. The development of FI-ICP-MS applied in environmental samples, biological samples and food samples were reviewed briefly. The development of microchip-based nanoflow injection, chip-based microflow injection and inductively coupled plasma mass spectrometry was also discussed. It indicates that the FI-ICP-MS will be applied and studied more and more widely in China with its rising economy and comprehensive national strength.
