Abstract
A device for determining and/or monitoring an analyte contained in a fluidic process medium. The device comprises a sensor, which contains a process membrane with a porous support structure, a luminescent substance, that comes into contact with the analyte or gaseous process medium, being embedded in said support structure, an emitter unit, whose radiation excites the luminescent substance, causing it to emit luminescent radiation, a receiver unit, which detects the luminescent radiation and a control/evaluation unit, which determines the concentration or the partial pressure or pressure of the analyte using the quenching of the luminescent radiation of the luminescent substance. According to the invention, the porous support structure comprises plastic, ceramic, metal or foamed plastic.
