Fourier Transform Infrared Spectrometer (FTIR) is most commonly utilized in medical sector for detection of proteins & analytes in sample. It is known to work on principle of detecting absorption of light at specific wavelength. This spectrometer has compact tabletop structural configuration and is easy to use. It uses ultraviolet rays that get absorbed in sample which is later measures for diagnostic purposes. Fourier Transform Infrared Spectrometer (FTIR) is also known to find application for gas chromatography and in geology sector.
