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 …

We maintain a facility for cosmogenic nuclide sample preparation for meteoric and in situ ²⁶Al and ¹⁰Be. This includes heavy liquid separation and cleaning of sample material with hydrochloric acid and hexasilicafluorid acid (HCl SiF₆) on shakers. Further leaching is carried out in low-concentrated hydrofluoric acid on hot dog rollers and in ultrasonic baths. Digestion of quartz-rich material is done on shaker tables and in a microwave digestion oven that ensure save operation. Ion-exchange …

Our laboratory is equipped with one of the latest sample digestion systems. The Multiwave can digest samples of all kinds - e.g. food, environmental, pharmaceutical and, of course, geological samples. The samples can be digested at up to 300°C and 200 bar in Teflon or quartz glass vessels at very low blank values. The vessel size is variable and can be adapted to the desired sample quantity.

The lab is equipped with various instruments for the preparation of sediment and soil samples.

Soil samples collected in the study area are placed in a plastic bag on site, sealed and labelled with a unique sample label. After sample storage, some pre-treatments have to be carried out before the physico-chemical investigation. Pre-treatment includes sample splitting, drying, sieving (< 2 mm for fine soil, see Soil Laboratory - Particle Size Analysis) and digestion. The sample is divided by a riffle divider or by quartering to the desired quantity. The samples are either dried in air …
