Solid polymer electrochemical technology is a revolutionary innovation in the field of electrochemical detection. In essence this technology is based on the principle of electrochemical catalytic reaction. As a general rule the sensors respond to the target gases and deliver a very small current signal that is usually proportional to the gas concentration. Usually, electrochemical sensors are using either a liquid or a gel electrolyte which leads to a couple of challenges during the operation of the sensor. The EC Sense solid polymer electrochemical sensors overcome these obstacles.EC Sense’s solid polymer sensors feature a composition of three electrodes in contact with the electrolyte. A typical electrode consists of a large surface area of precious metal and other materials. The electrode, electrolyte and the surrounding air are in contact while the gas diffuses through the back of the porous membrane into the working electrode of the sensor. At this electrode, the gas is oxidized or reduced. This electrochemical reaction causes a current to flow through the external circuit.
