Fourier Transform Infrared Spectroscopy uses infrared radiation to determine the chemical bonds present in the sample. Aspectrum of wavenumber and absorbance can be analyzed for the chemical composition of a sample. Organic molecules are most readily identified, making the FTIR an ideal tool for polymer identification and characterization. In addition to a standard transmission attachment, an attenuated total reflectance head allows for direct testing of solids and liquids without any sample preparation. The OMNIC software connected to the spectrometer allows for single and multi-component identification of the molecules and polymers in a sample by comparing the spectra gathered to stored libraries of data.
