ABSTRACT:
An arrangement for optical measuring concentration of substances has a measuring space which is composed of a material selectively permeable for particles to be measured, acting back on the particles and transparent for a measuring radiation, and a measuring space is arranged in working connection with the object to be measured and the measuring radiation passes through the measuring space. The measuring space has a layer that is a water-insoluble solvent or made of poly(ethylene terephthalate) or polytetrafluoroethylene. The layer excludes a reaction from the particles to be measured.
