We request instrumentation for a new ICP-MS laboratory that will be operated by three working groups, and will be open to other scientists on a cooperative basis. The requested instrumentation consists of 1) a triple-quad ICP mass spectrometer (TQ-ICP-MS), 2) a laser ablation system equipped with an ultra-high vacuum (UHV) cell, 3) a laser-induced breakdown spectroscopy (LIBS) system connected to the laser, and 4) an automated matrix removal / preconcentration system mainly for seawater samples. The instruments will replace the 20 year old laser ablation ICP-MS laboratory of our faculty, thereby meeting new analytical requirements and ensuring that the laboratory will be ready for the future. A major strength of our project is the integration of the different instruments into one laboratory for joint usage by distinct groups, each with a different analytical focus. This maximizes efficient usage of the equipment and increases scientific output. The new laboratory will allow for projects hitherto not possible and will open new analytical horizons: 1) The planned connection of the laser ablation system to an existing helium mass spectrometer as well as to a LIBS system is a new and innovative approach for our ongoing and future thermochronology-based projects. The in-situ analyses permit double- or triple-dating of single crystals, and simultaneous analysis of light elements that are difficult or impossible to analyze by ICP-MS, such as halogens. 2) The new laser instrumentation will allow for analyses at high spatial resolution and mapping of trace element distributions in single crystals, as required by some of our projects. 3) ICP-MS analyses of trace and ultratrace elements in seawater, pore water, and hydrothermal vent fluids become increasingly important for our work. This will be possible with the requested automated preconcentration system for online reduction of matrix load and increase of trace element concentrations. Overall a TQ-ICP-MS is the state-of-the-art analytical technique for trace element analysis on liquids and laser-ablated solids, with high innovative potential for new research developments. Its hallmarks are high sensitivity, low detection limits, excellent removal of mass interferences, and rapid mass scanning.

我们要求为一个新的 ICP-MS 实验室配备仪器，该实验室将由三个工作组运营，并将在合作的基础上向其他科学家开放。所需仪器包括 1) 三重四极杆 ICP 质谱仪 (TQ-ICP-MS)，2) 配备超高真空 (UHV) 单元的激光烧蚀系统，3) 激光诱导击穿光谱仪 (LIBS) ) 连接到激光器的系统，以及 4) 主要用于海水样品的自动基质去除/预浓缩系统。这些仪器将取代我们学院已有 20 年历史的激光烧蚀 ICP-MS 实验室，从而满足新的分析要求并确保实验室为未来做好准备。我们项目的一大优势是将不同的仪器集成到一个实验室中，供不同的小组联合使用，每个小组都有不同的分析重点。这最大限度地提高了设备​​的使用效率并增加了科学产出。新实验室将允许开展迄今为止不可能的项目，并将开辟新的分析视野：1) 计划将激光烧蚀系统连接到现有的氦质谱仪以及 LIBS 系统，这是我们正在进行的和 LIBS 系统的一种新的创新方法。未来基于热年代学的项目。原位分析允许对单晶进行双重或三次测年，并同时分析 ICP-MS 难以或不可能分析的轻元素，例如卤素。 2) 新的激光仪器将能够按照我们的一些项目的要求，以高空间分辨率进行分析并绘制单晶中的痕量元素分布图。 3) 海水、孔隙水和热液喷口流体中痕量和超痕量元素的ICP-MS分析对于我们的工作变得越来越重要。通过所需的自动预浓缩系统，可以在线减少基质负载并增加微量元素浓度，这将成为可能。总体而言，TQ-ICP-MS 是用于液体和激光烧蚀固体痕量元素分析的最先进的分析技术，对于新的研究开发具有很高的创新潜力。其特点是灵敏度高、检测限低、质量干扰去除效果好、质量扫描快速。
