Abstract

Biochemist and hospital laboratory supervisor Leonard Skeggs’ burst of insight in the early 1950s that ‘…[manually intensive clinical] analyses could be done in a continuously flowing stream’ [ 1 ] launched, and to a large extent defined, the field of automated clinical diagnostic testing for the quarter century that followed. Segmented analytical streams, in which air bubbles enhance within-segment mixing and minimize between-segment mixing, are the hallmark of Skeggs’ continuous flow (CF) analysis concept. [ 2 ] In 1975, Jaromir Ruzicka and Elo Hansen demonstrated the feasibility of performing CF analysis in non-air-segmented analytical streams. [ 3 ] This new approach to CF analysis, which they named flow injection analysis (FIA), launched a new wave of research and development directed primarily at bench-top analysis and environmental, industrial and pharmaceutical process monitoring applications. As described in this Research Front, CF analysis technology that has accrued over the past half century is well poised to meet global water quality monitoring needs in the present century. Terrestrial, estuarine and coastal waters are adversely impacted by substantial anthropogenic nutrient loads they receive from fertilized cropland runoff, confined animal feeding operation discharges, and municipal sewage outfalls. Globally burgeoning nutrient loads promote unsightly eutrophication
