由Ruzicka和Hansen等提出的流动注射分析(FIA)是湿化学快速自动分析的新成就。它能够以简单设备自动完成手工化学分析的大量工序,快速提供高质量化学成份信息。方法以特殊的样品注入方式,浓度梯度的控制、保留时间的高度重视为其基础特征。溶液混合不均匀、反应不完全以及读取连续变化的瞬时信号是FIA与经典化学分析的主要区别。
The flow injection analysis (FIA) proposed by Ruzicka and Hansen et al. Is a new achievement in rapid automated wet chemical analysis. It automates the extensive process of manual chemical analysis with simple equipment and quickly delivers high quality chemical composition information. The method takes special sample injection method, concentration gradient control and retention time as its basic characteristics. Inhomogeneous solution mixing, incomplete reaction, and reading continuous changes in the transient signal is the main difference between FIA and classical chemical analysis.
