Abstract: The present invention relates to a method and a device for fluorescence measurement of oil residues in water. The core of the invention is to use a powerful, narrow-band excimer lamp to excite intensive fluorescence radiation to detect the latter with a photodiode or the like, and to determine the oil concentration therefrom. The excimer lamp can be designed as a flat radiator a hollow cylindrical inner radiator or a tubular radiator, and can be combined with a through-flow or free fall measuring cell. The excimer lamp is advantageously operated in a pulsed or modulated fashion, the fluorescence radiation is measured at a right angle to the exciting radiation, the emitted and/or transmitted exciting light is monitored with the detectors, and a redundant measuring arrangement with a plurality of excimer lamps and fluorescence detectors is provided. The sensor is distinguished by reliability, freedom from maintenance and a long service life.
