近10年发展起来的流动注射分析(FlowInjeclion Analysis,下简称FIA)是连续流动分析(Continous Flow Analysis,下简称CFA)的一种模式。它与HPLC 亦很类似,可以看作是HPLC 与CFA 的一种“杂交”产物。HPLC的主要用途是分离及测定混合物;而FIA 主要用于测定样品中的一个或多个组分。与CFA 相比,FIA 有较高的样品容量、响应时间短、分析速度快,对于滴定或停流法有相当的潜力;在CFA 中使用气泡将液流分段,以避免样品在载 FlowInjeclion Analysis (FIA) developed in recent 10 years is a model of Continous Flow Analysis (CFA). It is also very similar to HPLC and can be considered as a “hybrid” product of HPLC and CFA. The main use of HPLC is to separate and determine mixtures; FIA is primarily used to determine one or more components in a sample. Compared to CFA, FIA has high sample capacity, short response time, high analysis speed and considerable potential for titration or stop-flow methods; the use of air bubbles in the CFA to segment the flow to avoid sample loading
