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.
