FTIR testing (Fourier-Transform Infrared Spectroscopy) is used to determine the spectral characteristics of solids, liquids, or gases. The analysis involves obtaining an FTIR spectral curve or spectrum that is searched against a spectral database containing thousands of polymers and organic compounds in an attempt to determine the composition or identity of the unknown sample. The technique is used to differentiate between different polymer types such as polypropylene, polyethylene, nylon to name a few.
How FTIR Testing Works
At its core, the intention of FTIR analysis involves obtaining detailed properties of certain unknown compounds and polymers that may be present in a particular material. When IR radiation excites a sample, some of the radiation is absorbed and some is transmitted resulting in a fingerprint of the functional groups present in the sample of interest. These fingerprints are unique to each material tested and therefore FTIR is very good at determining the composition and identity of a variety of chemical compounds. Because of the nature of this type of analysis as well as its success ratio, FTIR is also commonly used to identify polymers and other chemical compounds such as:
- Consumer grade products
- Plastics
- Rubbers
- Organic acids and salts
- Paints
- Coatings
- Petroleum products (unique oils and greases)
- Pharmaceutical products
