RECOVERABLE ENZYME SENSOR WITH REPLACEMENT MEMBRANE SYSTEM

摘要

A recoverable enzyme sensor is created by a body 3a of coroundum ceramics in the shape of a cylinder being terminated with a truncated taper 12 in which a reservoir 10 is created in the shape of cylinder with the base of circular ring inside of which both a current electrode 5 made of porous metal and electrolyte e.g. potassium chloride, are arranged; in the cross-section parallel with the basis line the first ceramics layer 17 of the reservoir 10 has the shape of cylinder in which a reference electrode 4 is arranged and further, the body 3 is covered with a covering membrane 9 and connected with the cover 2 created by the holder 1 equipped with at least one opening 14 in which there are arranged at least one enzyme membrane 8, at least one protecting membrane 11, and at least one control membrane 20.
