Abstract

Abstract Translated from German Um bei einer Anordnung zur optischen Messung von Stoffkonzentrationen die Messempfindlichkeit zu erhöhen und um im IR-Bereich messen zu können, ist ein Messraum aus einem für die zu messenden Teilchen selektiv permeierbaren, auf die Teilchen rückwirkenden und für die Messtrahlung transparenten Stoff vorgesehen, der in Wirkverbindung mit dem Messobjekt steht und der von der Messtrahlung durchstrahlt ist. In order to increase the measuring sensitivity in an arrangement for the optical measurement of substance concentrations and to be able to measure in the IR range, a measuring space is provided from a substance that can be selectively permeated for the particles to be measured, that reacts on the particles and that is transparent to the measuring radiation There is an active connection with the measurement object and which is irradiated by the measurement radiation.
