Acquisition of a Thermal Ionization Mass Spectrometer

该合同为纽约州立大学石溪分校(SUNY)地球和空间科学系运营和维护的自动化多收集热电离源质谱仪提供53%的采购成本。剩余的资金将由纽约州立大学系统提供。为继续开展涉及地球和空间科学系5名教员和约15名研究生的研究项目，有必要购置质谱仪系统。需要新仪器高精度、低丰度灵敏度和微量样品能力的研究领域包括：美国西南部第三纪火山活动；东太平洋隆起岩浆活动的地球化学研究；白云石成因的微量元素研究；密西西比山谷铅锌矿石的铅同位素研究；古海水和碳酸盐沉积物的氧、碳、锶、硼同位素丰度。

This award provides 53% of the acquisition costs for an automated multiple collection thermal ionization source mass spectrometer to be operated and maintained in the Department of Earth and Space Sciences at the State University of New York (SUNY) in Stony Brook. The remaining funds are to be provided by the SUNY system. The acquisition of the mass spectrometer system is necessary for the continuance of research projects involving five faculty members and approximately 15 graduate research students in the Department of Earth and Space Sciences. The research areas needing the high precision, the low-abundance sensitivity, and the micro-sample capabilities of the new instrument include: work on Tertiary volcanism in the southwest U.S.; geochemical studies of magmatism along the East Pacific Rise; trace element studies of the origin of dolomites; lead isotopic studies of the lead- zinc ores in the Mississippi Valley; and the oxygen, carbon, strontium and boron isotope abundances of ancient seawater and carbonate deposits.
