摘　　要：发光二极管诱导荧光检测器(LED-IF)是近十年来发展起来的一种微型化荧光检测器,在流动注射、毛细管液相色谱、毛细管电泳及芯片电泳等微流动分析系统中具有广泛的应用。本文讨论了LED-IF的4种光学结构,并对其主要器件,包括光源、滤光片、透镜、光纤、光电检测器以及检测池作了详细讨论,还介绍了LED-IF与其它技术的联用及其在生物、医药和环境样品检测中的应用,对未来的发展趋势作了展望。Light emitting diode induced fluorescence detector （LED-IF） has been developed and widely used as detectors in capillary flow systems, including flow injection analysis, capillary liquid chromatography, capillary electrophoresis and microchip analysis. This review summarizes the progress of LED-IF in recent years. Four kinds of optical arrangements are presented. The main parts of LED-IF, including light source, filter, lens, optical fiber, photo electronic detector and detection cell, are discussed in detail. The applications of LED-IF in bioanalysis, pharmaceutical analysis and environmental analysis are presented. Furthermore, the trend of development of LED-IF is also discussed.
