Abstract: Analytical apparatus comprises an electrolytic cell (10) comprising a counter electrode (12) and a reference electrode (14). Working electrodes (16, 18) are positioned equidistantly and symmetrically from the counter and reference electrodes. Currents through the electrolyte between the working electrodes and the cell wall are induced by energising the counter electrode through a differential amplifier (22). Further differential amplifiers (32, 34) coupled to the respective working electrodes provide analysis output signals at output terminal 30.

Abstract: An improved potentiostat for use with electrochemical cells provides dynamic protection of both the electrochemical cell elements and the sensitive potentiostat components from any significant voltage or current overload. A comparator compares the potentiostat input voltage with the electrochemical cell reference electrode voltage. When the reference electrode voltage becomes substantially different from the potentiostat input voltage and exceeds a certain preset value, the comparator activates a control means that causes the cell current to go to zero. This system provides dynamic protection even as the input voltage varies.
