Acquisition of an Ion Chromatograph for Hydrological, Geochemical and Biogeochemical Research

所有的生物都依赖于清洁水的供应。该奖项资助购买新的仪器，这些仪器将作为研究人员教学和研究任务的一个重要方面，通过提高他们量化水中化学成分的能力，并帮助确定什么？清洁？水才是。离子色谱，一种用于测量水中主要溶解离子的技术，已经被研究人员使用了吗？这些专题包括：农业做法对溶解成分去向和迁移的影响；岩石和土壤的化学风化以及小流域中碳的去向；人类对城市流域天然水的扰动；酸性环境中低温地球化学反应的影响；流体与岩石之间的二氧化碳相互作用；主要化学成分作为冰川、水文和生物地球化学过程示踪物的使用；以及气候变化对供水的影响。由该奖项资助的新仪器将扩大研究人员？在这些领域的分析能力，并提供更灵敏的检测下限的水中的化学成分。这一新的仪器收购不仅将支持五名研究人员及其学生的资助研究，也将支持由研究人员指导和建议的许多本科生进行的非资助研究。一个多学科的地球科学家小组将获得一台新的离子色谱仪，以支持他们在水文学、水文地质学、冰川学、实验水相地球化学、生物地球化学、气候变化动力学和环境地球化学方面的研究。他们的集体研究项目需要对天然地表水和地下水、冰川融化水、地下卤水、土壤提取物和实验溶液中的主要离子进行高质量的分析。新的最先进的仪器将带来更大的分析能力，更灵敏的检测极限，以及更多可能的分析对象，而12年多前的仪器为这些研究人员提供了很好的服务，但现在已经过时。

All living things depend upon the availability of clean water. This award funds the purchase of new instrumentation which will serve as an important aspect of the teaching and research mission of the researchers by enhancing their ability to quantify the chemical constituents in water, and help determine what ?clean? water is. Ion chromatography, a technique used for the measurement of major dissolved ions in water, has been used by the researchers? investigations of such topics as the impacts of agricultural practices on fate and transport of dissolved constituents; chemical weathering of rocks and soils and the fate of carbon in small watersheds; human perturbation of natural waters in urban watersheds; the impact of low temperature geochemical reactions in acidic environments; carbon dioxide interactions between fluids and rocks; the use of major chemical constituents as tracers of glaciological, hydrological, and biogeochemical processes, and impacts of climate change on water supplies. The new instrumentation funded by this award will expand the researchers? analytical capabilities in these areas and provide more sensitive detection limits of chemical constituents in waters. This new instrumental acquisition will support not only the funded research by the five researchers and their students, but also the unfunded research conducted by the many undergraduate students mentored and advised by the researchers. The new instrumentation will also support teaching goals introductory geochemistry courses.A multi-disciplinary group of Earth scientists will acquire a new ion chromatograph to support their research in hydrology, hydrogeology, glaciology, experimental aqueous geochemistry, biogeochemistry, climate change dynamics, and environmental geochemistry. Their collective research projects demand high-quality analyses of major ions from natural surface and ground waters, glacial meltwaters, subsurface brines, soil extracts, and experimental solutions. The new state-of-the-art instrument will bring expanded analytical capabilities, more sensitive detection limits, and greater variety of possible analytes than the 12+ year old instrument that has served these researchers well, but is now obsolete.
