Abstract
An electrochemical detector has an electrochemical thin-layer flow cell whose operation is based on the so-called wall-jet principle, in combination with a controller unit. The controller unit can apply a periodically changing voltage having a square wave voltage formation to a sensor electrode of the electrochemical cell such that a first potential level of the square wave functions as a detecting potential and a second potential level of the square wave functions as a cleaning potential.
