RUI: Establishment of an Inductively Coupled Plasma Mass Spectrometery (ICP-MS) Facility

该合同提供了购买电感耦合等离子体质谱计系统（ICP-MS）所需资金的一半，该系统将在乔治亚州立大学地质系安装和运行。大学承诺提供购置设备所需的剩余资金。该仪器用于痕量和超痕量元素和同位素比分析。它将由佐治亚州立大学的首席研究员及其同事使用，并将进行操作和管理，以便为需要快速准确的多元素分析方法的其他合格研究人员提供区域访问。需要ICP-MS能力的具体研究项目包括：(1)流体包裹体微量元素和稀土元素的测定及其在热液蚀变过程和矿床形成中的应用；(2)皮埃蒙特省水化学（溪流和地下水）研究；(3)人骨微量元素分析以重建古饮食；(4)其他地球化学研究。该仪器也将被纳入乔治亚州立大学地质系的教学中。＊＊＊

9405716 Ghazi This award provides one-half the funding required for the acquisition of an inductively-coupled plasma mass spectrometer system (ICP-MS) to be installed and operated in the Department of Geology at the Georgia State University. The University is committed to providing the remaining funds necessary for the acquisition of the equipment. The instrument is to be used for trace and ultra-trace elemental and isotopic ratio analysis. It will be used by the Principal Investigator and colleagues at the Georgia State University and will be operated and managed in order to provide access regionally to other qualified researchers needing a rapid and accurate method of multi-element analysis. Specific research projects requiring the capability of the ICP-MS include: (1) trace and rare earth element determination of fluid inclusions with applications to processes of hydrothermal alteration and the formation of ore deposits, (2) studies of water chemistry (stream flow and groundwater) within the Piedmont Province, (3) trace element analysis of human bone to reconstruct paleodiets, and (4) other geochemical research. The instrument will also be incorporated in the teaching of the Geology Department at Georgia State University. ***
