0731794RipleyThis grant provides partial support for a full time lab manager/technician for the Stable Isotopic Research Facility (SIRF) at Indiana University. Duties of the research technician include: 1) training of all users of laboratory facilities, 2) maintenance of mass spectrometers and associated gas preparation systems, 3) development of new analytical techniques, and 4) analyses of non-routine samples, especially those produced by laser ablation methods. This laboratory has expanded, and now houses four stable isotope ratio mass spectrometers with a variety of associated on-line sample preparation devices. These include a laser fluorination system, high-temperature combustion furnaces and related gas chromatographic systems for carbon and hydrogen isotopic analyses, elemental analyzers for sulfur, carbon, oxygen, hydrogen, and nitrogen analyses, water-CO2 equilibration and water to hydrogen conversion devises, and an automated carbonate-CO2 preparation system. In addition to on-line peripheral systems, the labs contain several traditional vacuum extraction systems. These include a CO2 laser fluorination system, a conventional BrF5 extraction line, a fluorination system for the preparation of SF6 SO2 lines for the preparation of large standard samples for both EA and dual inlet analyses, high-and low-temperature sequential carbon extraction lines, a system for the extraction of inclusion fluids and gases, and chromatographic systems for the isolation of various sulfur species. The research technician will be involved in the development of new analytical methods, and the training of undergraduate, graduate, and post-doctoral students. The activities of the research technician are closely tied to the enhancement of graduate research initiatives.

0731794Ripley这笔赠款为印第安纳大学稳定同位素研究设施 (SIRF) 的全职实验室经理/技术员提供部分支持。研究技术人员的职责包括：1) 培训实验室设施的所有用户，2) 维护质谱仪和相关气体制备系统，3) 开发新的分析技术，以及 4) 分析非常规样品，尤其是生产的样品通过激光烧蚀方法。该实验室已经扩建，现在拥有四台稳定同位素比质谱仪以及各种相关的在线样品制备设备。其中包括激光氟化系统、高温燃烧炉和用于碳和氢同位素分析的相关气相色谱系统、用于硫、碳、氧、氢和氮分析的元素分析仪、水-二氧化碳平衡和水到氢转化装置，以及自动碳酸盐-CO2制备系统。 除了在线外围系统外，实验室还包含几个传统的真空抽气系统。其中包括 CO2 激光氟化系统、传统的 BrF5 萃取线、用于制备 SF6 SO2 的氟化系统（用于为 EA 和双入口分析制备大型标准样品）、高温和低温顺序碳萃取线、用于提取包裹体流体和气体的系统，以及用于分离各种硫物质的色谱系统。 研究技术人员将参与新分析方法的开发以及本科生、研究生和博士后的培训。研究技术人员的活动与研究生研究主动性的加强密切相关。
