Voltammetric Ion Sensor
First Claim
1. A method for the quantitative determination of an ion in a fluid which comprises subjecting the fluid to voltammetry using a sensing electrode which comprises an electrically conducting support having a surface which is coated with a support matrix, the support matrix being a single layer containing (a) an electroactive species capable of being oxidised or reduced to form a charged species and (b) an ionophore, the support matrix having been obtained by drying a coating solution comprising the support matrix material, the electroactive species, and the ionophore;
- wherein the ionophore and the electroactive species are two different chemicals.
