Triple quad mass spectrometry with inductively coupled plasma (TQ-ICP-MS)

除其他外，耶拿大学的轮廓线LIFE专注于微生物交流，这是由建立的卓越集群“微观宇宙的平衡”进一步加强。生物、地球和材料科学交叉领域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通过质谱的扩展以一种面向过程的方式进行研究。该系统极大地扩展了对水溶液中元素的精确定量分析的可能性，而传统的单四ICP-MS无法测定或只能在有限的范围内测定。单颗粒测量模式和与惰性气体手套箱的耦合使化学分析直接或耦合到其他纳米颗粒检测系统（场流分馏，纳米颗粒跟踪分析或液相色谱）后，取决于单个颗粒大小。因此，在地球科学和生命科学中，可以对微粒结合污染物的环境行为做出更好的陈述和预测。此外，耦合激光烧蚀可以实现微米分辨率宏观界面的空间表征和时间变化。拟议中的大型设施将使新的研究项目成为可能，并以最先进的方法为年轻科学家的教学/资格做出重大贡献，从而支持大学的中心目标。

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.
