摘要: The present application discloses a sensor for determining a measurand correlated with a concentration of at least one analyte belonging to the class of reactive oxygen species in a measuring fluid, the sensor including a sensor element having an indicator substance, wherein the indicator substance is oxidized into an oxidized form of the indicator substance by the at least one analyte, a means for generating a flow of current in the sensor element that causes a reduction of the oxidized form of the indicator substance and thereby regeneration of the indicator substance, an optical measuring sensor to detect measuring radiation influenced by the oxidized form of the indicator substance and to generate an electrical measuring signal using the influenced measuring radiation, and a sensor switch connected to the optical measuring sensor to receive the measuring signal and to ascertain a measured value of the measurand using the measuring signal.

摘要: An optochemical sensor for measuring luminescing analytes in a measurement medium includes a sensor housing, a light source, a functional element, a photodetector and a control unit, wherein the sensor housing includes a window suitable for coming into contact with the measurement medium, wherein the light source is configured to emit a stimulation signal in such a way that the stimulation signal is partially emitted onto the functional element and the stimulation signal is partially emitted through the window into the measurement medium as to stimulate a first analyte present in the measurement medium, wherein the functional element includes a reference dye that includes an inorganic material and is suitable for emitting a first luminescence signal upon stimulation with the first stimulation signal.

摘要: A sensor element for an optochemical sensor includes: a luminescence indicator, whose luminescence can be quenched with oxygen; and scavenger units to deactivate singlet oxygen, forming a chemical reaction product by reacting with singlet oxygen, wherein the scavenger units are selected to be recovered by a decomposition reaction induced thermally, photochemically or by a pressure increase of the chemical reaction product formed by the reaction with singlet oxygen.
