In our lab we use a FTIR-spectrometer Vertex 80v manufactured by Bruker. It is equipped with various light sources, beam splitters and detectors to operate from 25.000 cm⁻¹ to 80 cm⁻¹. The maximum resolution is 0.25 cm⁻¹. An attached IR-microscope (Bruker Hyperion 2000) provides the possibility to perform unpolarized and polarized measurements on single crystals in the energy range of 25.000 cm⁻¹ to 420 cm⁻¹ with a spatial resolution of 20 µm.
Additional equipment: Heating/cooling stage …

The Environmental Mineralogy and Biogeochemistry Labs are equipped with a very diverse suite of spectroscopic and scattering instruments to determine material chemical composition, structure, surface area and grain size of both synthetic and natural samples. For instance,

• Our powder X-ray diffractometer (XRD) consists of two individual instruments capable of X-ray scattering analysis using both Cu (λ=1.54 Å) and Ag radiation (λ=0.56 Å) in transmission geometry. XRD can be used to analyze …
