ABSTRACT:
An analytical method using a sensor of the enzyme electrode type is provided for determining in a sample the concentration of an analyte reactive with an enzyme present on the sensor to produce an electrochemically active species detectable by the sensor, which comprises applying a potential across the sensor to cause an electrical current to flow therethrough, contacting the sensor with the sample thereby causing a change in the current flow and, when a working potential is applied across the sensor, determining the concentration of the analyte as a function of the change in the current characterized in that at some time before the working potential is applied and the concentration of the analyte is determined a potential significantly in excess of the working potential is applied, whereby to reduce the period required to establish a signal sufficiently stable to permit the determination to be effected.
