ICP-MS single cell application
The Chair of Applied Geology possesses comprehensive equipment for training and research in the field. It also possesses comprehensive and sophisticated equipment for instrumental inorganic analyses. On the one hand, this equipment is applied in research and training. On the other hand, it allows the acquisition of research funding.

Trace and ultratrace elements can be determined using ICP-MS in aqueous solutions and inorganic and biological nanoparticulate phases can also be characterised using single particle/single cell ICP-MS with regard to chemical composition, particle size and number of particles.
Particle size distribution and concentration of nanoparticle phases or specifically dyed nanoparticles can be investigated using (fluorescence) nanoparticle tracking analysis (fluo-NTA) . The LC-OCD-OND system can be used for the highly sensitive quantitative determination of colloidal and dissolved organic carbon and nitrogen compounds as well as nitrate and ammonium in liquid solutions. Solids can also be analysed with spatial resolution in combination with laser ablation.
Major and minor elements can be detected in aqueous solutions using ICP-OES , anionic contents in aqueous solutions can be detected using ionchromatography, UV-VIS photometry and titration.
Solid samples can be analyzed subsequent to microwave assisted pressure digestion or conventional pressure digestion as bulk samples or direct and spatially resolved by means of laser ablation coupled to ICP-MS. Sequential extraction can be used to estimate mobility and chemical bonding of heavy metals and radionuclides in soils.
The glovebox is in an argon atmosphere and is suitable for anoxic, H2O and CO2-free sample preparation of, for example, redox-sensitive, natural or CO2-sensitive, technical samples (e.g. cement). 2D measurements of pH, O2 and CO2 can be conducted with the VisiSens TD system with a high spatial resolution and a wide range of experimental design applications. For characterization of magnetominerals magnetic susceptibility and Curie temperature can be determined on solid materials.
