Among other things, the University of Jena with its profile line LIFE focuses on microbial communication, which is further strengthened by the established Cluster of Excellence "Balance of the Microverse". Interfacial processes in the intersection of bio, geo and material sciences are an integral part of this. Interactions of (micro-) organisms with their environment can be investigated in a process-oriented way with the expansion of mass spectroscopic possibilities. The proposed system greatly expands the analytical possibilities for the accurate quantification of elements in aqueous solution, which cannot be determined with conventional single quad ICP-MS or only to a limited extent. The single-particle measurement mode and coupling with an inert gas glove box enable chemical analyzes depending on the individual particle size directly or after coupling to other nanoparticle detection systems (field flow fractionation, nanoparticle tracking analysis or liquid chromatography). Thus, in both the geosciences and the life sciences, significantly better statements and predictions can be made on the environmental behavior of particulate-bound pollutants. Furthermore, the spatial representation and temporal change of macroscopic interfaces with μm resolution is possible by coupling with laser ablation. The proposed large facility will enable new research projects and contribute significantly to the teaching / qualification of young scientists with state-of-the-art methods and thus support a central goal of the university.
