Large equipment

Short Description

The ICP-MS system is installed in a clean room (Class 10.000) and provides the accurate determination of elemental concentrations in the range of mg/L to sub-µg/L in liquid samples. Solid samples can be analyzed after the application of fit-fort-purpose digestion methods.

The on-line combination of the ICP-MS system with the included high efficient size exclusion chromatographic system (Waters ACQUITY UPLC H-Class Bio) enables the investigation of metal/biomolecule interaction as well as the characterization of metalloproteins (metal/protein stoichiometry). Moreover, a variety of chromatographic separation techniques can be combined on-line with the ICP-MS system for elemental speciation analysis
