0345905EilerThis grant provides two-years partial salary support for a research technician in the laboratories for stable isotope geochemistry at the California Institute of Technology. This is a Phase II technician support grant under the Instruments and Facilities (IF) Program. The stable isotope geochemistry technician at Caltech, Nami Kitchen, will provide the following contributions to our facility: 1) training of students, postdoctoral fellows, and visiting scientists in the use of instruments within this laboratory, 2) maintenance of gas-source mass spectrometers and other experimental apparatus; 3) processing samples through established analytical procedures in support of research conducted by users of this laboratory; and 4) construction and refinement of components of new analytical apparatus. Her greatest specific scientific contributions will be to provide continuous productivity and quality control for two semi-automated analytical methods developed in our laboratories over the last two years: 1) laser fluorination of minerals and glasses, applied to projects in petrology, mantle geochemistry, paleoclimate studies, and geobiology; and, 2) on-line reduction and D/H ratio measurement of trace quantities of water released from geological and meteoritic samples. This second analytical method is a relatively recent development that we anticipate will be a foundation for an innovative and productive research program over the time-scale of this grant.***

0345905Eiler这笔赠款为加州理工学院稳定同位素地球化学实验室的研究技术人员提供两年的部分工资支持。 这是仪器和设施 (IF) 计划下的第二阶段技术人员支持补助金。 加州理工学院的稳定同位素地球化学技术员 Nami Kitchen 将为我们的设施做出以下贡献：1) 培训学生、博士后研究员和访问科学家如何使用本实验室内的仪器，2) 维护气源质谱仪及其他实验仪器； 3) 通过既定的分析程序处理样品，以支持本实验室用户进行的研究； 4）新型分析仪器部件的构建和完善。 她最大的具体科学贡献将是为我们实验室在过去两年中开发的两种半自动分析方法提供持续的生产力和质量控制：1）矿物和玻璃的激光氟化，应用于岩石学、地幔地球化学、古气候项目研究和地球生物学； 2）对地质和陨石样品中释放的痕量水进行在线还原和D/H比测量。 第二种分析方法是一个相对较新的发展，我们预计它将成为本次拨款期间创新和富有成效的研究项目的基础。***
