This proposal involves acquisition of replacement laboratory instrumentation for the Experimental and Analytical Geochemistry Laboratory (EAGL) in the Department of Geological Sciences at the University of Michigan. Several of EAGL's main analytical tools, a Leeman simultaneous ICP-OES, a Dionex ion chromatograph, UIC coulometric titrators, and a GBC dual beam spectrophotometer, have been used routinely in research and teaching since they were purchased in 1986, and are now in need of replacement. Walter's research group has made contributions in the areas of marine carbonate geochemistry, the geochemistry of natural waters, experimental geochemistry, and sedimentary basin hydrogeochemistry. Given EAGL's capabilities, the laboratory not only has served Walter's research group but others at the UM and elsewhere on a recharge basis, particularly researchers in aqueous chemistry, and marine biogeochemistry. It has been maintained by an Instrumental Analyst (50% institutional salary support) over the years and has accrued considerable experience in managing a productive research and educational facility. The EAGL has also had a broad societal impact in terms of working on practical problems (applied geochemistry, environmental problems, hydrocarbon and groundwater pollution and resource issues, climate change and human impacts on natural forested watersheds). Over the years, many graduate students have trained in the lab and have used the facilities to produce a variety of research studies, which have advanced the state of scientific knowledge. Furthermore, the hands-on training they received gave them the expertise and confidence to set up their own research laboratories at other institutions. The requested instrumentation includes a JY Horiba Ultima 2C ICP- OES, a Milestone Ethos Microwave Digestion Station, a Dionex DX 600 High Performance Ion Chromatograph with conductivity and photodiode array detector, a UIC Coulometrics Carbon Coulometer with additional acidification module, and a Perkin Elmer Lambda 25 UVNIS spectrophotometer. The acquisition of this new generation of equipment, with its quantum leap in analytical capability and ease of use, will facilitate even greater scientific research contributions, while at the same time having broader impacts on societal concerns, real-world applications, student education and training, and on mentoring the next generation of geoscientists.

这项建议涉及为密歇根大学地质科学系实验和分析地球化学实验室购置替换实验室仪器。EAGL的几个主要分析工具，Leeman同时ICP-OES，Dionex离子色谱仪，UIC库仑滴定仪和GBC双光束分光光度计，自1986年购买以来一直用于研究和教学，现在需要更换。沃尔特的研究小组在海洋碳酸盐地球化学、天然沃茨地球化学、实验地球化学和沉积盆地水文地球化学领域做出了贡献。鉴于EAGL的能力，该实验室不仅为Walter的研究小组服务，还为UM和其他地方的其他人提供补给，特别是水化学和海洋生物地球化学的研究人员。多年来，它一直由仪器分析师（50%的机构工资支持）维护，并在管理生产性研究和教育设施方面积累了相当丰富的经验。EAGL在解决实际问题（应用地球化学、环境问题、碳氢化合物和地下水污染和资源问题、气候变化和人类对自然森林流域的影响）方面也产生了广泛的社会影响。多年来，许多研究生在实验室接受培训，并利用这些设施进行各种研究，从而提高了科学知识的水平。此外，他们接受的实践培训使他们具备了在其他机构建立自己的研究实验室的专业知识和信心。所要求的仪器包括JY Horiba Ultima 2C ICP- OES、Milestone Ethos微波消解站、具有电导率和光电二极管阵列检测器的Dionex DX 600高效离子色谱仪、具有附加酸化模块的UIC库仑碳库仑计和Perkin Elmer Lambda 25 UVNIS分光光度计。这一新一代设备的采购，其分析能力和易用性的飞跃，将促进更大的科学研究贡献，同时对社会问题，现实世界的应用，学生教育和培训，并指导下一代地球科学家产生更广泛的影响。
