Fourier transform infrared (FTIR) analysis

Fourier transform infrared (FTIR) spectroscopy is a technique that involves a diversified range of fundamental frequencies. J.B.J. Fourier introduced fundamental methods in mathematics, which were eventually used in spectroscopy to make it more effective. FTIR spectroscopy consists of absorption, reflection, emission, or photoacoustic spectrum acquired by the Fourier transform of an optical interferogram. FTIR is a highly efficient analytical technique and can simultaneously identify a wide range of frequency components. When the power of Fourier transformation is integrated with spectrometers, the resultant technology enhances the device’s analytical potential. FTIR spectrometer consists of an interferometer as the core component. The speed of an FTIR spectrometer is proportional to the number of resolvable elements in the spectrum. Upon using various beam splitters and detectors, FTIR spectrometer can be made useful for different frequency ranges and cover ultraviolet, visible, near-, mid-, and far-IR regions.
