Flow-batch analysis

Since its inception, flow-based analysis has dramatically transformed the way that sample analysis is handled. What used to be manual, slow and prone to error has become automated, rapid and precise.Though many improvements and modifications have already been explored, a most promising development has been the flow-batch analyzer. Through use of an instantaneous stop-mixing chamber and computer-controlled, flow-based sampling, it achieves extraordinarily high sampling rates. We review its historical evolution, components, features and operation, and analytical applications.

► We review flow-batch analysis (FBA), a new in-flow analysis automation system. ► Flow-batch analysis (FBA) unifies techniques to achieve great practical flexibility. ► The instantaneous stop chamber allows discrete sampling and complete process control. ► Computerized analytical approach controls reagent/analyte valve timing commutation.
