Sensor for determining a of a concentration of reactive oxygen species dependent measured variable

摘要

The present invention relates to a sensor for determining a with a concentration of at least one analyte, which belongs to the class of the reactive oxygen species, in a measuring fluid, in particular a measurement fluid, correlated measured variable, comprises:a fluid to make contact with the measuring sensor element which is provided, which comprises an indicator substance, wherein the indicator substance intended, by the at least one analyte to an oxidized form of the indicator substance to be oxidized;Means for generating a current flow in the sensor element, which a reduction of the oxidized form of the indicator and thus a regeneration of the indicator substance causes;an optical measuring sensors, which is designed for this purpose, one of the oxidized form of the indicator measuring radiation is influenced to detect and on the basis of the measuring radiation which is influenced, in particular electrical, measurement signal; anda sensor circuit, which with the optical measuring sensors for the reception of the measuring signal is connected, and which is designed for this purpose, on the basis of the measuring signal to determine a measured value of the measured variable.n="36"
