Fourier Transform Infrared Spectroscopy
Fourier Transform Infrared Spectroscopy (FTIR) is an analytical technique used to identify mainly organic materials. FTIR analysis results in an absorption spectra which provides information about the chemical bonds and molecular structure of a material. The FTIR spectrum is equivalent to the “fingerprint” of the material and can be compared with cataloged FTIR spectra to identify the material.
FTIR analysis offers several advantages over other techniques.
A few examples of common materials identified by FTIR are shown below.
COMMON HOUSEHOLD ITEMS
- Cleansers and Detergents
- Baking Powders and Ingredients
- Thermosets (hard plastic)
- Elastomers (rubber)
- Thermoplastics (polyethylene (PE), polyvinyl chloride (PVC) and polystyrene (PS))
- Food Products
- Synthetic Fibers (acrylic, nylon, polyester, rayon)
- Natural Fibers (cotton, silk, wood)
THE FTIR ADVANTAGE
FTIR analysis offers several advantages over other techniques. It can be used to test solid or liquid samples. Compared to other analysis methods it requires little or no sample preparation and no chemicals or consumables. In many cases it is non-destructive.
