Phase II: Technician Support for Gas-Isotope Ratio Mass Spectrometer Laboratory

0217128张伯伦这笔赠款是给斯坦福大学地质和环境科学系稳定同位素地球化学实验室的一名技术支持人员。这笔补助金用于支付两年的工资费用。稳定同位素实验室拥有Finnigan-MAT Delta plus XR和252质谱仪，这两台仪器都可用于连续流动测量，并具有用于有机质和矿物的C、H和N同位素分析的在线燃烧设备。Finnigan-MAT 252还拥有UV和IR激光器以及相关的萃取线，用于分析硅酸盐和氧化物矿物中的氧同位素。技术支持人员将负责：1)协助激光线路的建设；2)质谱仪的日常支持和维护；3)培训学生、博士后研究员和教职员工使用本实验室；以及4)样品分析。***

0217128ChamberlainThis grant is for a technical support person for the stable isotope geochemistry laboratory in the Department of Geological and Environmental Sciences at Stanford University. The grant covers the costs of salary for two years. The stable isotope laboratory has Finnigan-MAT Delta plus XR and 252 mass spectrometers, and both are configured for continuous flow measurements and have on-line combustion devices for C, H, and N isotope analyses of organic matter and minerals. The Finnigan-MAT 252 also has UV and IR lasers and associated extraction lines for the analysis of O isotopes in silicate and oxide minerals. The technical support person will be responsible for: 1) assisting in construction of laser lines; 2) routine support and maintenance of the mass spectrometers; 3) training of students, postdoctoral fellows and faculty in the use of this laboratory; and 4) analysis of samples. ***
