Fourier Transform Infrared Spectrometer. Vertex 80 & Hyperion1000 by Brucker

Fourier Transform Infrared Spectrometer (FTIR) is an instrument which sends electromagnetic radiation of about 40000 to 50 cm-1 to a sample, with some radiation reflected, some absorbed, and some passed through as a function of the sample type, its physical and chemical properties. The resulting signal at the detector in reflection o transmission mode presents as a spectrum, which can be used for optical properties characterization, to identify and characterize unknown materials, contamination on or in a material (e.g., particles, fibers, powders, or liquids), even additives after extraction from a polymer matrix, oxidation, decomposition, or uncured monomers in failure analysis investigations. A special type of reflectance techniques, Attenuated Total Reflectance (ATR) is also available, which is based on a phenomenon of internal reflectance to propagate the incident energy.  Small areas of interest down to 10 micrometres and very thin films can be characterized this way.
