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...http://www.google.fr/patents/US4059406?utm_source=gb-gplus-shareBrevet US4059406 - Electrochemical detector system
