<p>Apparatus (2) for driving an amperometric electrochemical sensor, which apparatus (2) comprises a microelectrode (30), drive means (36) for the microelectrode, and signal processing means (3), the apparatus (2) being such that the drive means (36) supplies successive pulsed chronoamperometric different conditions to the microelectrode (30), the microelectrode (30) produces a sequence of different voltages consequent upon receiving the chronoamperometric different conditions and correlates the received chronoamperometric different conditions with their respective measurement circuits, and the signal processing means (3) interrogates only the current corresponding to a particular voltage in the sequence of different voltages and thereby produces a single sensor output corresponding to each separate voltage in the sequence of different voltages whereby interrogation of the amperometric electrochemical sensor is facilitated.</p> |
