Abstract
An electrochemical flow-through detector with indium–tin oxide interdigitated microelectrode arrays was used for the determination of catecholamines. This detector showed amplification of the current signals by redox cycling. The undesired response due to ascorbic acid can be eliminated by coating the electrode surface with Nafion.Keywords
