Electronic circuit for analyzing the operation of electrochemical cells.

摘要

O An electronic instrument for use with an electrochemical cell that provides IR compensation while operating as either a galvanostat or a potentiostat The instrument includes an electronic circuit 10 having two output terminals, an input differential amplifier circuit 22, an output differential amplifier circuit 30, a control differential amplifier circuit 38, a reference differential amplifier circuit 48, a resistor, electric circuitry connecting the input terminal of the control amplifier to the instrument output terminal and a double pole, a double throw switch means 56. In a preferred embodiment, the electric circuitry connecting the control amplifier to the instrument output terminal is a potentiometer.
