A spectroscopic sensor assembly for detecting at least one predefined analyte constituent of a measurement fluid, the sensor assembly including a sensor housing; a radiation source; a detector device; a barrier assembly, which is transmissive for measurement radiation and is impermeable to the analyte constituent; a polymer matrix, which absorbs and releases the analyte constituent; a reflector assembly, which has a signal side facing the polymer matrix and facing the barrier assembly; the reflector assembly has a passage extending through the reflector assembly, through which passage the analyte constituent is exchanged between a measurement environment and the polymer matrix, which polymer matrix is located on the signal side of the reflector assembly; the reflector assembly reflects incident measurement radiation back toward the apparatus portion; the sensor assembly having a spacing means different from the polymer matrix that is designed to prevent the reflector assembly from approaching the barrier assembly.

Sensor assembly for spectroscopically detecting substances

A sensor arrangement includes a reaction subassembly having a housing and a detector subassembly. The housing is a layered component arrangement encompassing a luminophore-containing reaction laminate excitable, by irradiation with a first electromagnetic radiation of a first wavelength, to emit a second electromagnetic radiation of a second wavelength different from the first wavelength; and a temperature-detection laminate emitting an infrared radiation. The housing includes an opening for introducing a fluid, a reaction window and a temperature-sensing window. The reaction window transmits the first and second electromagnetic radiation, and the temperature-sensing window is penetrable by infrared radiation. The detector subassembly encompasses a radiation source emitting the first electromagnetic radiation, a radiation detector detecting the second electromagnetic radiation, and an infrared detector detecting, through the temperature detection window, the infrared radiation emitted from the temperature detection laminate. The reaction laminate and the temperature-detection laminate are embodied separately.

Device for the temperature-compensated optical detection of an oxygen content of a fluid

Described is an oxygen permeable layer for detection of molecular oxygen, wherein the layer has a carrier material in which at least one particle is comprised, wherein the carrier material is polyvinylidene fluoride or a copolymer of polyvinylidene fluoride, and the particle comprises a polymer or a copolymer, wherein the polymer or copolymer of the particle has a chemically covalently bonded indicator compound for detection of molecular oxygen. In addition, a multilayer system for detection of molecular oxygen is described. Also described are a method for producing the layer, and the use of the layer or of the multilayer system for detection of molecular oxygen.

Layers for the detection of oxygen

A method is provided for degradation-compensated evaluation of detection signals of a sensor arrangement operating on the principle of luminescence quenching, which arrangement has a luminophore that degrades over time, an excitation radiation source, and at least one optical sensor. The luminophore radiates, in accordance with a response characteristic of the sensor arrangement, in reaction to irradiation with a predefined modulated excitation radiation and as a function of the extent of an interaction of the luminophore with a quencher substance that quenches the luminescence of the luminophore. A response radiation is detected by the at least one optical sensor. The sensor arrangement outputs a detected intensity value representing an intensity of the response radiation and a detected phase value representing a phase difference of the response radiation with respect to the modulation of the excitation radiation. A predetermined calibration value correlation is identified in consideration of the reference response characteristic.
