Method Description:

Fourier Transform Infrared Spectroscopy (FTIR) is an instrument used in the identification and characterization of organic compounds. It is used often in the packaging industry for the analysis of material purity monomers and polymers such as polyethylene, polyester, nylons etc. It can be used to investigate powders, liquids, pills and multi-layer coatings. It is also used for forensic analysis in the identification foreign materials in products by matching unknown spectra with known compounds.

At first, the analysis was limited by the thickness of the samples, their shape, as well as their bulk quantity. This limitation has been largely solved by the use of changes in the presentation of the samples to the IR beam. Attenuated Total Reflectance (ATR) and Diffuse Reflectance accessories allow the analysis of the surface of the coatings and to compare the bulk properties with the surface properties of materials.
