Claim 0:
1. A method for self-regulating a suppressor of an ion chromatography system, the method comprising:
setting a power supply to provide an offset voltage VOS to the suppressor;
activating the power supply to provide an applied voltage waveform VA to the suppressor in addition to the offset voltage VOS;
commencing an ion chromatography run on the ion chromatography system in which an eluent flows through the suppressor;
measuring a current of the suppressor responsive to the offset and applied voltages VOS and VA during the ion chromatography run;
determining a suppressor state of the suppressor based upon the measured current in response to the offset voltage; and
adjusting the offset voltage VOS based upon the suppressor state, wherein (a) offset voltage VOS is increased for an unsuppressed state, and (b) offset voltage VOS is maintained for a suppressed state.
