概述流动注射分析(f.j.a.)是多种试液的快速连续分析的一种新技术。流动注射分析原理似乎很简单:液体样品以适当的固定区域的形式注射入非封闭载流中,载流运载此区域到检测器,检测器连续记录吸光度、电极电位和其它物理参数,并转变成流动池中分散样品区的透射的结果。最简单的f.i.a.分析仪(图1a)包括推进装置(如蠕动泵), Overview Flow Injection Analysis (f.j.a.) is a new technology for rapid and continuous analysis of a wide range of test solutions. The principle of flow injection analysis seems simple: a liquid sample is injected into a non-enclosed current-carrying flow in the appropriate fixed area and current-carrying the area to a detector that continuously records absorbance, electrode potential and other physical parameters and transforms into The result of the transmission of scattered sample areas in the flow cell. The simplest f.i.a. analyzer (Figure 1a) includes a propulsion device (such as a peristaltic pump)
