The Fourier Transform Infrared Spectroscopy (FTIR) is a method to to obtain an infrared spectrum of absorption, emission, photoconductivity or raman scattering of a solid, liquid or gas. It collects simultaneously spectral data in a wide spectral range. This instrument from LINSEIS combined a LINSEIS thermal analyzer with a FTIR is useful in applications such as chemical, pharmaceutical industry, polymers, etc.
