摘要： A method of measuring a sample that includes at least one reactant that can be oxidised and reduced between at least one working electrode and a counter electrode. The method involves: applying across the working and counter electrodes a cycle of at least three pulses, and measuring current at the working electrode during each pulse, wherein the at least three pulses comprise at least one over-potential pulse that has an amplitude equal to or greater than an oxidation or a reduction peak potential of the reactant; at least one under-potential pulse of amplitude less than the at least one over-potential pulse, and at least one other over-potential pulse or under-potential pulse.
