“…A narrow definition of the method has been adopted to keep this article within bounds. Thus, several important closely related methods have been omitted, notably the work of Mottola et al (43)(44)(45)(46)) with a recycling system and that of Pungor et al (47,48) on potential measurement, both of which have helped to open up an examination of the potentialities of nonsegmented CFA.…”

Since Skeggs' classic work (1) it has been generally assumed that air segmentation of the flowing stream and attainment of a "steady state" signal are essential parts of continuous flow analysis (CFA). Recently, RGzicka and Hansen (2) in Copenhagen and Stewart et al. (3)(4)(5) in Washington, D.C., have independently performed similar experiments of injecting the sample directly into the carrier stream, and

“…When the reaction, employed for the nonkinetic analysis is slow, reversible, or involves an additional interfering consecutive reaction, an initial reaction rate kinetic method may be advantageous. Dutt, Hanna, and Mottola (101) have applied their novel flow-through cell and flowthrough loop system for the repetitive and continuous photometric determination of iron (II) in lake water and tap water. The determination of iron(II) is based on the fast chemical reaction with ferrozine taking place in the detection zone and the washing out of the signal as a result of the imposed flow.…”
