Flow injection is now a widely used tool in the analytical laboratory for sample presentation to a range of optical and electrochemical detectors (Ruzicka & Hansen 1988; Valcarcel & Luque de Castro 1987). In addition to this basic but none the less important function, it provides a means to perform on-line physical and chemical treatment of the sample. Physical techniques such as dialysis and solvent extraction can significantly improve the total analysis time by minimizing off-line manual operations (Worsfold 1988). Chemical techniques can improve both selectivity and sensitivity and in this regard incorporation of solid phase reactors is particularly important, e.g. immobilized enzymes and antibodies and oxidation and reduction columns can be used to chemically modify the sample and ion-exchange resins and solid adsorbents can be used to preconcentrate the analyte or remove matrix interferences (Worsfold 1988).
