The Earth Materials group operates a Bruker IFS28 infrared spectrometer equipped with a Bruker A590 infrared microscope. The instrument can be used to acquire spectra from both powdered samples dispersed in KBr and individual free-standing mineral grains. Spectra can be recorded from 600 - 6000 cm^-1 with a spatial resolution of at least 30 µm. The main applications of infrared spectroscopy, in the Earth Materials group, are the identification of the defect site of H₂O in nominally anhydrous mantle minerals such as olivine and the quantification of H₂O and CO₂ in silicate glasses.
