FTIR stands for Fourier transform infrared. When IR radiation is passed through a sample, some radiation is absorbed by the sample and some passes through. The resulting signal at the detector is a spectrum representing a molecular "fingerprint" of the sample. The utility of infrared spectroscopy comes from different chemical structures (molecules) that produce different spectral fingerprints.

 

Advantages

  • FTIR covers a wide range of chemical applications, especially for polymers and organic compounds.
