Technician Support for the Stable Isotope Laboratory at Florida State University - Phase I

这项拨款为佛罗里达州立大学（FSU）稳定同位素实验室的一名技术人员提供了三年的支持。 前苏联稳定同位素实验室，这是位于国家强磁场实验室，是我们的地球化学和环境计划的研究生/本科生研究和PI的研究，其中涵盖了广泛的研究兴趣，包括古饮食的确定，古海洋学的研究，古生态学和古气候重建，土壤中的碳和营养循环的检查，森林和湿地生态系统，调查食物网和营养相互作用，以及研究湿地和垃圾填埋场的甲烷氧化。 该实验室拥有最先进的稳定同位素比质谱仪和四个外围仪器，包括气体工作台II设备，高温转换元素分析仪，CarloErba元素分析仪和气相色谱仪。这些不同的外围仪器与质谱仪连接，可以测量各种样品中碳、氮、氧、氢和硫的稳定同位素比率。 该技术员将在管理稳定同位素实验室方面发挥关键作用，并协助不太熟练的用户安全操作质谱仪和相关仪器。技术人员将培训新用户，并确保质谱仪系统、真空管线和其他实验室设备的顺利操作和适当维护，这将使实验室能够为校园内和其他机构的学生、教职员工和其他调查人员组成的庞大而高度多样化的社区提供服务，特别是佛罗里达A M大学，这是一所位于一英里内的历史悠久的黑人大学。 技术人员还将协助推广计划，如REU计划和青年学者计划。

EAR-0517806WangThis grant provides three years of support for a technician for the Stable Isotope Laboratory at the Florida State University (FSU). The FSU Stable Isotope Lab, which is located in the National High Magnetic Field Laboratory, is a key part of our Geochemistry and Environmental program for both graduate/undergraduate research and the research of the PIs, which cover a wide diversity of research interests, including determination of paleodiet, study of paleooceanography, reconstruction of paleoecology and paleoclimate, examination of carbon and nutrient cycling in soils, forests and wetland ecosystems, investigation of food web and trophic interactions, and study of methane oxidation in wetlands and landfills. The lab has a state-of-the-art stable isotope ratio mass spectrometer and four peripheral instruments including a Gas Bench II device, a high temperature conversion elemental analyzer, a CarloErba elemental analyzer, and a gas chromatograph. These various peripheral instruments are interfaced to the mass spectrometer, allowing measurements of stable isotopic ratios of carbon, nitrogen, oxygen, hydrogen and sulfur in a broad range of samples. The technician will play a critical role in managing the stable isotope laboratory and will act as a facilitator for safe operation of the mass spectrometer and associated instruments by less adept users. The technician will train new users and ensure the smooth operation and proper maintenance of the mass spectrometer system, vacuum lines and other laboratory equipment, which will enable the laboratory to serve a large and highly diverse community of students, faculty and other investigators on campus and from other institutions, particularly Florida A&M University a historically black University located within a mile. The technician will also assist outreach programs such as the REU program and the Young Scholar Program.
