The hydrothermal diamond-anvil cell (HDAC) can be applied to study fluids, solids and particularly aqueous samples in situ at high pressures and temperatures. Although such cells are usually used at P-T conditions of less than 3 GPa and 850 °C, experiments with aqueous fluids to 23 GPa and 1025 °C have been reported in the literature.
Because diamonds are transparent over a large range of the electromagnetic spectrum, samples in the HDAC can in principle be studied using any "photon-in – …

In principle, an internally heated pressure vessel (IHPV) consists of a thick-walled pressure vessel sealed by closure plugs at the ends. In addition, there is a pressure inlet/outlet as well as several electrical leads into the vessel for power supply to and temperature control of the internal furnace. The equipment is particularly designed for experimental studies at medium to high temperatures (currently up to 1250 °C) and pressures up to 10 kbar. This P-T range is inaccessible by …

The laboratory is equipped with two confocal high-resolution Raman spectrometer systems to study fluid and solid samples (from single point analyses and line scans to two- and three-dimensional Raman imaging) at ambient pressure and temperature and over a wide range of P-T conditions.
Available sample environments are three Linkam heating/cooling stages and two hydrothermal diamond-anvil cells.

The determination of angles and intensities produced by diffraction of X-Ray radiation by mineral lattices provides information, which is characteristic for their crystalline structures. X-Ray powder diffraction is used by for identification, quantitative phase analysis and structure refinement of phases in synthesized powders. Most diffraction data is processed by the Rietveld method using the GSAS software package.
The lab includes two STOE Stadi P diffractometer equipped with a curved …
