Acquisition of Irm-GC-MS Instrumentation for Global Biogeochemical Research

9977414这个授予南卡罗来纳大学哥伦比亚分校的主要研究仪器奖为全球生物地球化学研究提供了一个同位素比质谱仪。它将特别用于化合物特定同位素地球化学的研究，这是一个在追踪环境系统中化学转移和物质分配途径方面特别重要的新领域。南加州大学教师的研究计划包括研究现代海洋沉积物和土壤、过去的海洋和气候条件、自然水域中溶解的有机物质、挥发性气体和有机污染物的循环，以及地球内部的地球化学研究。几个将使用该系统的研究项目已经在南加州大学进行，但需要在其他实验室进行分析；这将是南卡罗来纳州第一个具有气相色谱与质谱仪集成能力的此类仪器，以便进行特定于化合物的分析。该设施还将在收回成本的基础上向外部研究人员开放。该项目得到了国家科学基金会海洋科学部的支持。南卡罗来纳大学将为项目总成本的30%提供成本分摊支持。*

9977414GoniThis Major Research Instrumentation award to University of South Carolina at Columbia provides an isotope ratio mass spectrometer for global biogeochemical research. It will be particularly used for research into compound-specific isotope geochemistry, a new field of particular importance in tracing pathways of chemical transfer and material partitioning in environmental systems. Research plans by USC faculty include study of modern marine sediments and soils, past oceanographic and climatic conditions, dissolved organic material in natural waters, cycling of volatile gases and organic pollutants, and study of the geochemistry of the earth's interior. Several research projects which will use the system are already underway at USC, but require that the analyses be carried out at other laboratories; this will be the first such instrument in the state of South Carolina with a capability for gas chromatography integrated with the mass spectrometer to allow the compound-specific analysis. The facility will also be available to outside researchers on a cost-recovery basis. The project is supported by the Division of Ocean Sciences at NSF. University of South Carolina will provide cost-share support for 30% of total project costs.***
