✦ Synopsis

A dual-electrode voltammetric/amperometric detector for flow-injection systems is described. The detector provides qualitative voltammetric information without the charging currents associated with scanning the potential. Selectivity is enhanced relative to direct voltammetric detection at a single electrode because only chemically reversible redox couples are detected. A preliminary evaluation with hexacyanoferrate(II1) and ascorbic acid is presented.

The change in peak current resulting from the reaction of Fe(I1) with nitroso-R salt in a flow-injection system is used to quantify Fe(I1) with either single-or dual-electrode amperometric detectors. The current change varies linearly with Fe(I1) concentration from 0 to 200 mg 1-l. The relative stan
