Abstract

See full text

A probed-solution disturbance controller includes an interface for receiving a solution sample signal from a probe in communication with a probed solution and an ion state detector that determines an ion state relative to a tip of the probe disposed for sampling the solution. The ion state is determined based on at least one of a measure of ion buildup or an estimate of ion buildup relative to the tip of the probe. A processor for the probed-solution disturbance controller is configured to cause disturbance of the probed solution responsive to the solution sample signal from the probe. The processor is adapted to control when the disturbance of the solution is activated relative to a next sample event. The processor controls at least one of following: disturbance duration; disturbance amplitude; disturbance start time; or disturbance stop time.
