A system for self-regulating a suppressor includes an ion chromatography suppressor, a power supply for applying an electric potential to the suppressor, and a control unit configured to provide an offset voltage VOS and an applied voltage VA to the suppressor, measure a current of the suppressor responsive to the offset and applied voltages VOS and VA, determine a suppressor state of the suppressor based upon the measured current, and adjust the offset voltage VOS based upon the suppressor state. A method for self-regulating a suppressor is also disclosed.
