FTIR is a technique used primarily for analysis of organic compounds, but it can be used for determining the chemical structure of inorganic compounds as well. Because chemical bonds absorb infrared energy at specific wavelengths, the basic structure of compounds can be determined by the spectral locations of their IR absorptions. Our FTIR instrument, IlluminatIR, is interfaced with a light microscope and attenuated total reflection (ATR) objective that allows spectra collection by directly contacting the diamond piece at the end of the objective with the sample. The ATR mode allows regions as small as 15 mm to be simultaneously observed and analyzed for identification of functional groups present in the molecular structure.
