Because the shape of this transient signal depends on the physical and chemical kinetic processes occurring in the carrier stream during the time between injection and detection, we include flow injection analysis in this chapter.

It covers chemical kinetic methods using reaction rates, radiochemical methods using radioactive decay, and flow injection methods where samples react and move with carrier streams. Chemical methods are useful for slow reactions and enzyme analysis; radiochemical methods utilize isotopes, and flow injection is ideal for fast sample processing.

FIA involves injecting samples into a flowing carrier stream, leading to transient signals at a detector, influenced by physical and chemical processes. The chapter outlines FIA's theory, describing components like propelling units, injectors, detectors, and transport systems. Applications span environmental and clinical analyses.
