Abstract

In ac polarography the measured signal often contains random fluctuations, usually referred to as noise. When the faradaic current is studied the noise becomes more and more disturbing when the concentration of the electroactive species decreases, and close to the detection limit the noise starts to mask the faradaic signal.
