Fourier Transform Infrared (FTIR)

A technique that uses infrared light to identify and analyze the composition of materials.

How It Works
  • FTIR uses modulated mid-infrared energy to shine on a sample
  • The sample absorbs the infrared light at specific frequencies
  • The FTIR spectrometer collects the data and generates a spectrum
  • The spectrum is compared to a reference database to identify the material
