Acquisition of a Secondary Ion Mass Spectrometer for Applications in Earth and Space Materials Research

9871270 Leshin该合同提供部分资金用于购买二次离子质谱仪（西姆斯或离子微探针），该质谱仪将安装在亚利桑那州州立大学地质系并运行。 亚利桑那州立大学和美国国家航空航天局承诺提供收购所需的剩余资金。 该仪器能够对天然固体样品中的微量元素和稀有同位素进行精确的原位定量分析，空间分辨率约为10微米。 新的离子微探针将主要用于一系列调查的研究和研究生一级的教学，这些调查涉及太阳系的早期历史、行星大气、地球上以及可能的其他行星上生命的起源、陆地岩浆的起源以及水流体在环境地球化学和成岩作用中的作用。

9871270LeshinThis award provides partial funding for the acquisition of a secondary ion mass spectrometer (SIMS or ion microprobe) that will be installed and operated in the Geology Department at Arizona State University. Arizona State University and the National Aeronautics and Space Agency are committed to providing the remaining funds necessary for the acquisition. The instrument is capable of precise in situ quantitative analysis of trace elements and rare isotopes in natural solid samples, with spatial resolution of approximately ten microns. The new ion microprobe will be devoted mainly to research and graduate-level teaching in a range of investigations dealing with the early history of the solar system, planetary atmospheres, the origin of life on earth and, possibly, other planets, the origin of terrestrial magmas, and the role of aqueous fluids in environmental geochemistry and diagenesis.***
