Isotopic information plays an increasing role for the investigation of processes in chemistry, biology, medicine, geology and environmental sciences. A simultaneously obtain information about relevant trace elements in the samples under investigation often improves the information content dramatically. The system we apply for in collaboration with 4 partners is a combination of a Multicollector-ICP-MS and a TripleQuad-ICP-MS which allows for a simultaneous analysis of isotope ratios and concentrations of trace elements after elimination of interferences. Samples will be introduced either as liquids (nebulizer, chromatography unit) or solids (laser ablation, ETV-coupling). During the next years we will focus on the following topics: (a) precise quantification of element concentrations in solid materials with  1 % uncertainty by isotope dilution analysis / Preparation of reference materials wirh different elements for a spatially resolved analysis on the micro- and nanoscale (fields of application:: plant and animal tissues, new materials) (b) Isotope and trace element determination in pure substances (W, C, Si) after coupling with ETV ( method developments) (c) Investigation of bacteriologically/enzymatically regulated processes during bioleaching (Isotopic systems: S, Fe, Re, Os and other PGE) (d) Establishing of routine methods for the determination of Hf-Isotopy in Magmatits, Sr-Isotopy in Carbonatits, the sediment delivery area analysis (main and trace elements with REE), as well as the investigation of single minerals (Apatite, Calcite, Mica, Feldspar, Garnet, Rutile, Titanite, Zircon) (mineral chemistry and isotopy -B, Li, Lu-Hf, Pb, Rb-Sr, U-Pb) (e) Isotope and trace element analysis in solutions with high salt concentrations (application fields mining, battery production and recycling, environmental sciences) (Isotopy systems: B, Li, S, Mg) for the investigation of the provenance of raw materials, the influence of processing parameters during production and recycling, as well as the extension of the thermodynamic datenbase THEREDA, which is applied for calculations of ongoing or potential dissolution and crystallization processes in salt formations. (f) Investigation of implant materials, degradation-, transport- and storage processes in organisms with spatially resoved analysis and after application of isotopically enriched starting materials (resorbable implant alloys based on Fe and Mg; Isotopy systems: Mg, Fe, Gd, Nd, Ag)

同位素信息在化学、生物学、医学、地质学和环境科学的过程研究中发挥着越来越重要的作用。有关所研究样品中相关微量元素的同时信息通常会极大地提高我们合作申请的系统的信息内容。与 4 个合作伙伴的合作是 Multicollector-ICP-MS 和 TripleQuad-ICP-MS 的组合，可在消除干扰后同时分析同位素比率和痕量元素浓度。样品将以液体形式引入。 （雾化器、色谱单元）或固体（激光烧蚀、ETV 耦合）在接下来的几年中，我们将重点关注以下主题：(a) 通过同位素稀释分析精确定量固体材料中的元素浓度，不确定度为 1%/。制备含有不同元素的参考材料，用于微米和纳米尺度的空间分辨分析（应用领域：植物和动物组织、新材料）(b)与 ETV 耦合后纯物质（W、C、Si）中的同位素和微量元素测定（方法开发） (c) 研究生物浸出期间的细菌学/酶促调节过程（同位素系统：S、Fe、Re、Os 和其他 PGE） (d) 建立测定岩浆岩中的铪同位素、碳酸岩中的锶同位素、沉积物输送区分析（主要元素和微量元素）的常规方法REE），以及单一矿物（磷灰石、方解石、云母、长石、石榴石、金红石、钛矿、锆石）的研究（矿物化学和同位素-B、Li、Lu-Hf、Pb、Rb-Sr、U- Pb) (e) 高盐浓度溶液中的同位素和微量元素分析（应用领域采矿、电池生产和回收、环境科学）（同位素系统：B、Li、 S、Mg），用于研究原材料的来源、生产和回收过程中工艺参数的影响，以及热力学数据库 THEREDA 的扩展，用于计算盐中正在进行或潜在的溶解和结晶过程(f) 通过空间解析分析并在应用同位素富集起始材料（基于铁和镁的可吸收植入合金；同位素系统：Mg、Fe、Gd、Nd、Ag）
