It is shown that the steady-state voltammetric behaviour of uncharged substrates for the unusual conditions of highly dilute support electrolyte can be simply determined by using spherical microelectrodes. Ohmic losses are small and calculable so that simple two-electrode cells can be used. The reverse process of the discharge of an ion of the dilute electrolyte is not symmetric with respect to the voltammetry of uncharged substrates (due to migration effects) but again leads to simple voltammograms. The use of electrodes of small dimensions therefore opens the way for the study of a wide range of new systems.
