Fourier Transform Analysis Applications

Fourier Transform Infrared (FTIR) Absorption Analysis


Fourier Transform Infrared analysis is based on the same physical measurement principle as nondispersive infrared analyzers (NDIR). The FTIR spectroscopy technique is able to determine the composition of complex mixtures of chemicals and is more accurate than NDIR analysis. This is possible because the absorption spectra of the materials are linear and additive. FTIR can make use of libraries of known spectra to interpret a complex spectrum.

Because of the broad range of applications for the Fourier Transform Infrared technique, the assistance of the BAGGI technical team is required in developing a specific application.

Typical applications can be:

  • Stack gas analyzers.
  • Polymer processing from input streams to final product.
  •  Gasoline composition.
