FTIR Spectrometers

In the disciplines of organic synthesis, polymer science, petrochemical engineering, the pharmaceutical sector, and food analysis, FTIR spectrometers are widely used. Furthermore, since FTIR spectrometers and chromatography may be combined, researchers can use such equipment to look at the workings of chemical reactions and the detection of unstable chemicals. A source, an interferometer, a sample compartment, a detector, an amplifier, an A/D converter, and a computer make up a typical FTIR spectrometer. Radiation from the source causes the sample to go through the interferometer and end up at the detector. The signal is then amplified and transformed into a digital signal by an analog-to-digital converter and an amplifier, respectively. The signal is eventually sent to a computer, where the Fourier transform is run.
