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.

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.
