High speed, power ponentiostat/galvanostat with ir compensation for use with an electrochemical cell
An electrochemical 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 having two output terminals, an input differential amplifier circuit, an output differential amplifier circuit, a control differential amplifier circuit, a reference differential amplifier circuit, a resistor, electric circuitry connecting the input terminal of the control amplifier to the instrument output terminal and a double pole, double throw switch means. In a preferred embodiment, the electric circuitry connecting the control amplifier to the instrument output terminal is a potentiometer.
