FTIR (Fourier Transform Infrared Spectroscopy)

FTIR can characterize a solid or liquid product (Nicolet iS50 FTIR™ device) . It is a non-destructive technique, which does not require sample preparation, except grinding for solids samples. The resulting spectrum reflects the molecular vibrations under the light effect as a function of wavelength. The results are the peaks related to functions of the molecule such as OH, CH, C = O, COO-, C = C, C≡C, C≡N, NH, NH₂, etc. This technique makes it possible to characterize organic compounds as well as inorganic ones. Although it is a qualitative method, it can be used for quantitative measurement under certain conditions.
