一概述流动注射分析(F_(LOW)-I_(NJECTION)A_(NALYSIS)简称 FIA)是在 Skeggs 的空气分隔流动比色分析系统(示于图1)的基础上发展起来的。1975年丹麦学者 Ruzicka 和 Han-sen 废除了 Skeggs 系统中引入气泡的做法,采用注射进样,从而发展为 FIA 新分析系统,于图2所示。FIA 分析系统即可连续进样,也可定点快速进样,突出特点是:(a)分析速度快,一般为100～200个样/h,最高速度报导为1200个样/h。(b)消耗试剂、试样量小:准确测量试剂耗量不超过500μl,试样在100μl 之内,进样最少可至
An overview of flow injection analysis (F_ (LOW) -I_ (NJECTION) A_ (NALYSIS) referred to as FIA) is based on the Skeggs air separation flow colorimetric analysis system (shown in Figure 1) developed on the basis of. In 1975, Danish scholars Ruzicka and Han-sen abolished the introduction of air bubbles in the Skeggs system and injected injection to develop a new FIA system, as shown in Figure 2. FIA analysis system can be continuous injection, but also rapid injection of fixed-point, outstanding features are: (a) analysis speed, usually 100 ~ 200 samples / h, the maximum speed reported as 1200 samples / h. (b) Consumption of reagents, small sample size: accurate measurement of reagent consumption does not exceed 500μl, the sample within 100μl, the injection can be at least to
