Since the introduction of attenuated total reflection (ATR) spectroscopy for characterization materials, attempts have been made to relate measured reflectivity ( R ) absorption coefficient ? absorbing material interest. The common approach is limited low case under...

Abstract. Infrared attenuated total reflection (ATR) spectroscopy is a common laboratory technique for the analysis of highly absorbing liquids and solids, variety ATR accessories FTIR spectrometers are available. However, rarely found in industrial processes, where compact, robust, cost-effective sensors continuous operation required. Here, narrowband photometers more appropriate than instrume...
