Fourier transform infrared (FTIR) spectroscopyers since tresearch has been available to researchers since the early 1970s. FTIR spectroscopy is based on interferometry and makes use of the complete source spectrum rather than the individual wavelengths generated by grating and/or prism systems used in conventional IR spectroscopy (van de Voort, 1992). An IR spectrum represents a fingerprint of a sample with absorption peaks which correspond to the frequencies of vibrations between the bonds of the atoms making up the material. Because each different material is a unique combination of atoms, no two compounds produce the same IR spectrum. Therefore, IR spectroscopy can result in a positive identification (qualitative analysis) of every different kind of material. In addition, the size of the peaks in the spectrum is a direct indication of the amount of material present. With intuitive software algorithms, infrared is an excellent tool for quantitative analysis.
