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.

除其他事项外，耶拿大学及其概况线的寿命集中在微生物交流上，这是由卓越的卓越群体“微不足道的平衡”进一步加强的。生物，地理和物质科学交集中的界面过程是其中不可或缺的一部分。 （微 - ）生物与环境的相互作用可以随着质谱可能性的扩展而以过程为导向的方式进行研究。提出的系统大大扩展了分析可能性，以准确地量化水溶液中的元素，该元素无法用常规的单四元ICP-MS或仅在有限的程度上确定。单粒子测量模式并与惰性气杂志盒耦合，可以直接或与其他纳米颗粒检测系统（田间流量分级，纳米颗粒跟踪分析或液相色谱法）耦合，从而实现化学分析。在地球科学和生命科学中，都可以对特定结合污染物的环境行为做出明显更好的陈述和预测。此外，通过激光消融，可以通过μM分辨率的宏观接口的空间表示和暂时变化。拟议的大型设施将实现新的研究项目，并通过最先进的方法为年轻科学家的教学提供了重大贡献，从而支持大学的核心目标。
