Description
An infrared spectrophotometer is used to identify materials including organic polymers. Infrared spectrophotometers record the relative amount of energy as a function of the wavelength/frequency of the infrared radiation when it passes through a sample. Therefore, chemical structures of different samples will reflect differences in the IR absorption spectrum allowing for identification and characterization of a sample. Unlike a dispersive spectrometer, an FTIR spectrometer or FTIR spectrophotometer is used to simultaneously obtain the whole spectral data of a sample.
