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.
