Abstract
There is a strong demand for on-line monitoring in modern process automation. Transferring analytical methods from laboratory to production plants is still a problem, since for many laboratory devices do not exist corresponding process-capable measuring instruments. The developed MIR-ATR sensor solves this problem in case of FT-MIR spectroscopy (wavelength range 2.5 μm to 25 μm or wavenumber range 4000 cm-1 to 400 cm-1). A prototype of this sensor was constructed in order to determine the alcohol and sugar concentration in the brewing and beverage industry. Furthermore, the consumption of carbon source sugar can be monitored during yeast fermentations. The sensor can easily be adapted to a wide range of chemical, pharmaceutical and biotechnological processes by exchanging the analyte specific optical band pass filters.
