This lab is dedicated to mineral synthesis and other experiments using mostly inorganic chemistry or hydrothermal synthesis methods. The lab is equipped with standard chemical laboratory equipment such as analytical balance, centrifuge, fume hood, furnaces, hotplate stirrers, ovens, dry block heater, pH meters as well as reflux setups and sonicator bath. Hydrothermal synthesis is possible in closed Teflon lined cells heated either conductively or by microwave irradiation.

This lab is dedicated for the synthesis of redox-active iron mineral phases, as well as their interaction with redox-sensitive trace elements (e.g., As, Cr,) and anaerobic microbes, under oxygen-limited conditions. It is equipped with two anaerobic chamber workstations, setup for liquid degassing to remove O₂, sample autodiluter for trace element analysis and standard chemical laboratory equipment such as analytical balance, centrifuge, fume hood, hotplate stirrer, shaking incubator, oven and …

This lab is dedicated to mineral and mineral precursor synthesis using organic chemistry or advanced inorganic chemistry methods requiring special conditions, such as anoxic and/or anhydrous atmosphere or the use of hazardous chemicals. For this purpose it contains all the equipment necessary to perform almost any chemical process reasonably expected in synthetic chemistry. The lab is also used to produce starting materials to be used in other projects if obtaining them commercially is …

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 Mineral Synthesis Lab complex is 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.

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 section is well equipped for rock crushing, sieving and milling, preparation of thin and polished sections and grain mounts, and mineral separation by gravimetric and magnetic methods. We maintain central facilities and equipment for cleaning, crushing, sieving and grinding rock samples, both for preparation of homogenized whole rock powders and for the production of mineral separates. Whole rock powders (grain sizes < 62 μm) are typically used for X-Ray diffraction (XRD), X-Ray …

An X-Ray Diffraction analysis is a method in which a beam of X-Rays is usually directed at a fine powder of randomly oriented grains of crystalline substances. The X-Rays are scattered in directions that depend on the crystal structure of the sample and the resulting X-Ray diffraction pattern can uniquely identify the material. The method is used to identify individual minerals in randomly oriented bulk rock powder samples (grain sizes < 62 μm for qualitative analysis, < 10 μm for quantitative …

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 …
