Fourier-transform infrared

FT-IR stands for Fourier transform infrared. Once a sample exposed to IR radiation, some radiation is absorbed by the sample and some passes through (is transmitted). The IR absorbed and transmitted is a spectrum representing a sample ‘fingerprint’.

A few examples of common materials identified by FT-IR are Cleansers and Detergents, Paints, Oils, Paper, Gel, Glue, Epoxy, Resin, Fibers (Synthetic and Natural), Plastics, Elastomers (rubber). FT-IR is a very powerful technique to characterize the chemical composition. As the FT-IR measurement is non-destructive other analytical technique might be applied afterwards.
