It is equipped with a precision sample positioning mechanism, viewports and spare ports for future equipment. Potassium bromide glass ports are included and the system is prepared for use with the Bruker Optics Inc and ThermoFisher. infrared spectrometers. Other commercially available spectrometers may be interfaced on request. The innovative design enables not only reflection- absorption infrared spectroscopy (RAIRS) measurements at grazing incidence on well-defined, perfectly flat substrates, but also allows supports IR measurements in transmission mode for polycrystalline powder samples. Special PTS (or Flag Style style sample holders) dedicated for infrared investigations available.
