AMPEROMETRIC DETECTION OF LACTATE: A COMPARISON BETWEEN MEDIATED AND PLATINISED CARBON ELECTRODES
Abstract
Two electrode configurations,for the amperometric determination of lactate, were investigated using the enzymelactate oxidase. One system was based on theuse of mediators (1,2-dimethylferrocene or tetrathiafulvalene) and the other system incorporated a platinised carbon electrode. Overall the platinised carbon electrodes proved to be the most stable sensors. During a period of 136-days the electrodes maintained their range, linearity and response times. The electrodes retained a low sensitivity for ascorbic acid. Further optimisation and incorporation of the electrodeinto a flow injection analysis system is now being carried out.Citation
