Acid digestions of solid samples for main and trace element analysis are carried out in a modern digestion laboratory with special digestors that are also suitable for working with hydrofluoric and perchloric acid. The samples can be prepared as open digestions using the DigiPrep heating block system (SCP Science) or as closed digestions using the Multiwave 5000 microwave reaction platform (Anton Paar).
The Vitriox Electric 4+ fusion unit from Fluxana is available for the production of glass …

Cathodoluminescence microscopy is a technique to visualize in minerals and materials heterogeneities and internal structures that are invisible using pure optical methods (reflected and transmitted light microscopy). Internal structures of minerals become visible and are indicative of growth zoning, trace element zoning and structures allowing processes such as mineral growth, resolution and alteration to be reconstructed. Furthermore, it helps to rapidly distinguish optical similar minerals, …

Jaw crushers are available for crushing rocks and other geological samples. Various mills (vibrating disc mill, McCrone mill) are available for further processing, which pulverize the granulates for further analysis.

The Electron Microprobe lab offers non-destructive chemical analyses of solids using a JEOL JXA-8200 Electron Probe Microanalyzer (EPMA) with an EDX detector. The microprobe is capable of quantitatively measuring the abundance of all elements from C to U using five wavelength-dispersive spectrometers (WDS) and an energy-dispersive X-Ray spectrometer (EDX) for rapid analyses. This analytical technique combines micron-scale chemical analyses with scanning electron microscopy and is capable of …

The Electron Microprobe Lab houses a JEOL JXA-8500F electron microprobe that is equipped with a field-emission cathode, five wavelength-dispersive X-Ray spectrometers, and an energy-dispersive spectrometer. Electron microprobe analysis (EMPA) is mainly used to quantitatively investigate the chemical composition of rocks and mineral phases in the micrometer to centimeter range.
Typically, polished sections of rocks or minerals are used for this purpose, but highly vacuum-resistant fossil …

By using this elemental analyzer (Euro EA 3000) it is possible to determine the concentration of nitrogen, carbon and hydrogen in solid samples. The substance to be analysed is digested by an oxidative combustion of samples packaged in tin foil. The combustion takes place explosively in a highly oxygen enriched He atmosphere. Gases that generated during the combustion are led by the carrier gas (helium) into the separation column. CO₂, H₂O, N₂ and SO₂ are separated chromatographically within …

The Laboratory hosts four laboratory chamber furnaces of type K114 up to 1100 °C from Heraeus - Thermo Science. Additionally there are two high temperature furnaces type HTRV 70-250 up to 1600 °C from Gero. And it also contains two high temperature furnaces type HT 04/17 up to 1750 °C from Nabertherm.

The HT-HP-Laboratories comprises a vertical gas-mixing furnace (Carbolite-Gero STF 16/180) for for synthesis of glasses or crystals under controlled oxygen fugacity (f₀₂ conditions). Gas mixtures of CO, CO₂ and Ar/H₂ are possible or experiments can be run under atmospheric conditions.
The laboratory further includes diamond anvil cells (DAC) and laser heating needed for own and collaborators' high pressure and high temperature research. In detail, there is a suite of different types of …

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 – …

ICP-OES is an analytical method for the determination of elements in the concentration range from μg/l to g/l. The ICP-AES laboratory uses an ICP5100 with vertical dual view (VDV) from Agilent. By using a vertically arranged torch is it possible to observe the plasma in both directions axial and radial. The simultaneous measurement of all elements of interest enables a short measurement time. This allows a high sample throughput and the processing of very small sample volumes as well.
The …
