amperometric gas sensor for the selective determination of partial pressures of a gas

摘要

it is a amperometrischer gassensor for selective determination of partialdru00fccken a gas with high precision is described.such a gassensor consists of a solid electrolyte and inert electrodes.in the solid electrolyte sensor is so selectedthat when you create an electric current or a voltage therein with the gas ions to be determined in a secondary gleichgewichtsreaktion in training an electrically measurablea signal to form a reaction product. preferred solid electrolytes are na + - '' - alumina, nasicon, cubisch stabilised zirconia and zirconia polykristalle of tetragonalen.it is also a method for selective determination of gases using such electrodes are described.it is preferably an electric power or power used, a periodic signal, in particular in the form of a saw tooth or sinus, the solid electrolyte sheetthus the formed reaction product in the same degree will be reduced, as before, was built.
