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 …

The Geochemistry group is equipped with clean laboratory facilities used for low-blank sample preparation and element separation for isotope abundance measurements and concentration determinations of different elements in rock samples and minerals. Pre-filtered air using various pre-filters and HEPA (H13) filters are employed as well as a slight overpressure, compared to the outside air, to produce clean-lab conditions. Our Clean Laboratory (a total of ca. 105 m²) consists of two separate …

Here we perform high-temperature and high-pressure digestions:

• Parr pressure vessels,
• Borosilicate glass Carius tubes at 220-250 °C and 320 °C (reverse aqua regia for Re-Os, PGE, Au),
• Quartz glass vessels in high-pressure asher HPA-S up to 320 °C (reverse aqua regia for Re-Os, PGE, Au),
• Glassy carbon vessels in high-pressure asher HPA-S up to 260 °C (HF-HNO₃).
