Vortragsankündigung: Am Mittwoch den 21. Juni 2000 findet am Lehrstuhl für Bioverfahrenstechnik folgender sehr interessante Vortrag statt: Vortragender: Dr. Ingo Klimant Institut für Analytische Chemie, Chemo- und Biosensorik, Universität Regensburg Thema: Neue Trends und Anwendungen in der fluoreszenz-optischen Sensorik Optical sensing techniques becames more and more attractive during the last years. This was mainly due to the availability of small and inexpensive optoelectronical components and new smart sensing concepts. Thus calibration free, small and inexpensive sensors can be realised. Her an overwiew is presented on new concepts for optical sensors based on time resolved luminescence techniques. Examples for sensors of determination of oxygenation, pH, carbon dioxide, temperature and salinity were given. Furthermore application examples are discussed. Its includes the contactless sensing of chemical parameters in closed systems, 2-D imaging of chemical parameters and fiber optic microsensors.
