Acquisition of Mass Spectrometers for Trace Elements and Isotopic Research in Marine and Earth Sciences

PIS申请资金购买电感耦合等离子体质谱仪（ICP-MS）和同位素比值监测-气相色谱仪/质谱仪（irm- GC/MS）。他们建议将这两种仪器作为机构设施（“成本中心”）进行操作，由专门的管理人员负责日常操作、维护和培训新用户。这些设施将受到由海洋化学、古海洋学和岩石学代表组成的科学管理委员会的监督。ICP-MS的具体应用包括分析水、沉积物、岩石和海洋微化石中的长寿命放射性核素、稀土、铂族元素和其他微量元素。irm-GC/MS将满足两个一般需求——13C和15n的化合物特定同位素测量和13C、15n和34s的微尺度测量。这些测量结果将应用于当代和古海洋的研究。WHOI将分摊29万美元，占该项目总资金的47%。* * *

9601587 Bacon The PIS request funding to acquire an Inductively Coupled Plasma-Mass Spectrometer (ICP-MS) and an isotope ratio monitoring-Gas Chromatograph/Mass Spectrometer (irm- GC/MS). They propose to operate both instruments as institution facilities (`cost centers') with dedicated managers for daily operations, maintenance and training of new users. The facilities will be under the supervision of a scientific management committee consisting of representatives from marine chemistry, paleoceanography, and petrology. Specific applications for the ICP-MS include analysis of long-lived radionuclides, rare earths, platinum group elements and other trace elements in water, sediment, rocks and marine microfossils. The irm-GC/MS will fulfill two general needs - compound specific isotopic measurements of 13C and 15 N and microscale measurements of 13 C and 15 N and 34 S in bulk samples. These measurements will be applied to studies of the contemporary and paleo oceans. WHOI will cost share $290,000, which represents 47% of the total funding for this project. ***
