Technician Support of the Stable Isotope Laboratory The University of Michigan

9405720 Lohmann该奖项提供部分资金支持分配到密歇根大学地质科学系稳定同位素实验室的技术人员。实验室仪器包括四台运行质谱仪，用于分析无机和有机样品中氢、碳、氮、氧和硫的稳定同位素比率的提取线，以及用于从小样本量中提取氧气的激光氟化系统。地质科学系有大量的研究生、教师研究员和博士后在他们的研究中使用稳定同位素测量作为主要的分析工具。此外，该实验室还接待了异乎寻常的大量来自美国和国外的访问科学家。实验室的巨大研究生产力现在需要一名全职技术人员的协助，他将协助操作和维护，培训用户和开发新技术。该实验室分析数据的研究应用主要集中在全球变化和环境地球化学领域。＊＊＊

9405720 Lohmann This award provides partial funding to support a technician assigned to the operations of the stable isotope laboratory in the Department of Geological Sciences at the University of Michigan. The laboratory instrumentation includes four operating mass spectrometers, extraction lines for analysis of the stable isotope ratios of hydrogen, carbon, nitrogen, oxygen and sulfur in inorganic and organic samples, and a laser fluorination system for oxygen extraction from small sample volumes. A large number of graduate students, faculty researchers and postdoctoral fellows in the Department of Geological Sciences employ stable isotope measurements as the main analytical tool in their research. In addition, the laboratory hosts an unusually large number of visiting scientists from the U.S. and abroad. The large research productivity of the lab now requires the assistance of a full-time technician who will assist with operation and maintenance, training of users, and with the development of new techniques. Much of the research applications of the analytical data from this laboratory are in the area of global change and environmental geochemistry. ***
