Acquisition of an ICP Magnetic Sector Mass Spectrometer

9304159 Halliday 该奖项提供开发质谱仪系统所需资金的 45%，该系统将激光烧蚀采样源与等离子体电离和多收集器扇形磁质谱仪结合起来。该系统的开发将优化各种地质样品的微量分析空间分辨率以及痕量元素和同位素灵敏度方面的分析性能。它将在密歇根大学地质科学系安置和运营。密歇根大学致力于提供开展该仪器开发项目所需的剩余资金。 该仪器将扩展现有的微量元素和同位素分析能力，并将应用于包括通过铷-锶放射性衰变法对微观流体包裹体进行测年、小样品的镥-铪同位素地球化学、陆地和地外物质的过渡元素地球化学以及确定硅质岩浆生产率的精确地质年代学等研究。 ***

9304159 Halliday This award provides 45 percent of the funds required for the development of a mass spectrometer system that will combine a laser ablation sampling source with plasma ionization and a multi- collector magnetic sector mass spectrometer. The system will be developed to optimize analytical performance with respect to microanalytical spatial resolution as well as trace element and isotope sensitivity for a wide range of geological samples. It will be housed and operated in the Department of Geological Sciences at the University of Michigan. The University of Michigan is committed to providing the remaining funds needed to carry out this instrument development project. The instrument will extend existing capabilities for trace element and isotopic analysis and will be applied to research including the dating of microscopic fluid inclusions by the rubidium-strontium radioactive decay method, lutetium-hafnium isotope geochemistry of small samples, transition element geochemistry of terrestrial and extraterrestrial materials, and precise geochronology to determine the production rates of silicic magma. ***
