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

除其他事项外，耶拿大学以其独特的生产线生命专注于微生物交流，这一点因建立的卓越集群“微宇宙的平衡”而得到进一步加强。生物、地球和材料科学交叉点的界面过程是其中不可或缺的一部分。随着质谱学可能性的扩大，(微生物)与其环境的相互作用可以以面向过程的方式进行研究。该系统极大地扩展了水溶液中元素的准确定量的分析可能性，而传统的单四元电感耦合等离子体质谱不能或仅在有限范围内测定水溶液中的元素。单颗粒测量模式和与惰性气体手套箱的耦合使化学分析能够直接或在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)之后根据单个颗粒的大小进行分析。因此，在地球科学和生命科学中，都可以对颗粒结合污染物的环境行为做出明显更好的陈述和预测。此外，通过与激光烧蚀耦合，可以实现μm分辨率的宏观界面的空间表示和时间变化。拟议的大型设施将支持新的研究项目，并大大促进使用最先进方法的年轻科学家的教学/资格认证，从而支持该大学的一项核心目标。

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.
