The RWI Geochemistry Lab is devoted to the chemical analyses of solid phases (rocks, soils, minerals, cement, bentonite etc.) after performing various selective or complete extraction and digestion techniques. Depending on the given problem a complete or element-specific so-called "wet chemical" analysis of a solid material can be produced. The analytical techniques applied to digest and extract solutions are the same as for groundwater samples with the analytical methods accounting for the different solution matrices.
