Abstract

Mid-Infrared (MIR) spectroscopy is an extremely reliable and well recognized fingerprinting method. Far-Infrared (FIR) and THz spectroscopy is quite difficult since it requires special sources, quasi optics, special materials and sensitive detectors. The technique of Attenuated Total Reflectance (ATR) has in recent years revolutionized solid and liquid sample analyses because it combats the most challenging aspects of infrared analyses, namely sample preparation and spectral reproducibility. An attenuated total reflection accessory operates by measuring the changes that occur in a totally internally reflected infrared beam when the beam comes into contact with a sample. In this work a spectral measurements using the ATR-FTIR technique will be presented. Spectral measurements of liquids and powders in the THz regime will be discussed and analyze. Furthermore, we will present ATR-FTIR spectral measurements that were carried out for commercial companies.
