Equipment Upgrade for the NCSU Light Stable Isotope RegionalAnalytical Facility

方案概要：海洋仪器方案支持获取用于收集、处理和分析海洋数据的仪器的请求。NCSU的这项提案要求为升级质谱仪设施的设备提供资金。质谱仪最初是在1984年购买的，资金来自海洋仪器计划(OCE83-10579)和ONR。所要求的升级包括基尔单酸浴自动碳化反应系统和全自动多端口系统。基尔系统是分析小型碳酸盐样品所必需的，自动化多端口将允许无人值守、自动操作，从而提高设施的效率。NCSU将提供此次采购50%的成本分担。该仪器将改进对小样本量碳酸盐的分析，这些碳酸盐对海洋学研究越来越重要。它将作为共享设施进行维护和运营。PI完全有资格获得、维护、操作和管理仪器。由大学分担费用是适当的。

Program Summary: The oceanographic instrumentation program supports requests to acquire instrumentation for the collection, processing and analysis of oceanographic data. This proposal from NCSU requests funding for equipment to upgrade a mass spectrometer facility. The mass spectrometer was originally purchased in 1984 withfunding from the oceanographic instrumentation program (OCE83-10579) and ONR. THe upgrades requested include a Kiel single acid bath auto-carbonated reaction system and fully automated multiport system. The Kiel system is necessary to analyze small carbonate samples, and the automated multiport will allow unattended, automatic operation, increasing the efficiency of the facility. NCSU will provide 50% cost-sharing this purchase. The instrument will improve the analysis of small sample-size carbonates which are increasingly important for oceanographic studies. It will be maintained and operated as a shared-use facility. The PI is well qualified to acquire, maintain, operate and manage the instrument. Cost sharing by the University is appropriate.
