流动注射分析（f.i.a.）的一些最令人兴奋的最新进展。已经涉及梯度技术，其基于在空间和时间上受控的分散的关键作用，基于识别和选择分散样品区的可再现的合适部分并利用这些点处的特定浓度用于分析目的的可行性。对这些技术进行了全面的回顾;除了公认的f.i.a.滴定和停流反应速率程序，已经开发了用于梯度稀释和校准、梯度扫描和选择性评估的方法。最后，详细描述了f.i.a.，提出了一种没有运动部件和零死体积的流体动力喷射器。
Some of the most exciting recent advances in flow injection analysis (f.i.a.) have involved gradient techniques, which, founded on the key role of the dispersion controlled in space and time, are based on the feasibility of identifying and selecting reproducibly suitable sections of the dispersed sample zone and exploiting the specific concentrations at these points for analytical purposes. A comprehensive review of these techniques is given; in addition to the well established f.i.a. titrations and stopped-flow reaction rate procedures, methods have been developed for gradient dilution and calibration, gradient scanning, and selectivity evaluation. Finally, a detailed description of the most recent development within f.i.a., a hydrodynamic injector with no moving parts and zero dead volumes, is presente.
