  • Patent number: 4215940
    Abstract: Monochromatic excitation light is passed into an indicator chamber to exc the indicator therein. The side of the indicator chamber in contact with the substance to be analyzed is closed off by a membrane which is permeable to the component of that substance whose concentration is to be determined. The side through which the radiation emitted from the indicator towards the light-measuring unit of the apparatus passes is transmissive for the emitted radiation. The direction of introduction of monochromatic excitation radiation, and the direction in which the radiation emitted from the indicator towards the light-measuring unit, include an angle relative to each other, and are preferably perpendicular.
