Fourier Transform Infrared Spectroscopy (FTIR)

Fourier Transform Infrared Spectroscopy (FTIR)

FTIR is used to identify primarily organic compounds, such as polymers. Samples are presented with IR energy, and the signals generated (based on a material’s unique interactions with energy) provide a molecular fingerprint (i.e. FTIR spectrum). This spectrum allows us to identify organic and some inorganic materials. At Gateway, we use FTIR microscopes, ATR (Attenuated Total Reflectance – for larger samples and surface analysis) and a large sample compartment style spectrometer.
