Equipment for identifying functional groups of organic materials and certain structures of solid and liquid samples using Fourier transform infrared (FTIR) spectroscopy in the spectral range of 400 cm^-1 to 10,000. It is prepared to collect 60 spectra per second at a resolution of 16 cm^-1 and it can work in transmission mode or attenuated total reflectance (ATR) with temperature control between 25 °C and 200 °C.
