MRI: Acquisition of an Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES) for a Diverse Range of Scientific Applications in Greater Saint Louis

圣路易斯大学的Paul Bracher教授及其同事Daniel Warren和Elizabeth Hasenmueller获得了来自主要研究仪器(MRI)和化学研究仪器和设施计划的这一奖项，从而获得了一台电感耦合等离子体光学发射光谱仪(ICP-OES)。该仪器是用于识别和量化溶液中金属的必要分析工具。因此，它在生物溶液分析、供水和流域、食品生产和化学反应等方面有着广泛的应用。该仪器还用于对本科生和研究生进行这一基本工具的培训。它能够开展公民科学实践活动，如分析当地的水供应，并向圣路易斯大学社区以外的其他研究人员提供。该建议旨在加强各级的研究和教育，特别是圣路易斯大学的研究人员在以下领域的研究和教育：(A)无机阳离子在生命起源中的预期作用；(B)地表水、浅层地下水和土壤的地球化学；(C)矿化组织中的离子交换与生理pH调节；(D)地球科学，以了解水、空气、土壤和岩石界面上的关键区域的水的转化；(E)道路盐污染的运输；(F)使用示踪剂，来自下水道溢流的废水污染，以及(G)在爬行动物、两栖动物和哺乳动物中，矿化组织如何缓冲酸碱平衡的扰动。

With this award from the Major Research Instrumentation (MRI) and Chemistry Research Instrumentation and Facilities Programs, Professor Paul Bracher from Saint Louis University and colleagues Daniel Warren and Elizabeth Hasenmueller have acquired an inductively coupled plasma optical emission spectrometer (ICP-OES). This instrument is a necessary analytical tool used to identify and quantify metals in solutions. Consequently, it has broad use in applications such as analysis of biological solutions, water supplies and watersheds, food production and chemical reactions. The instrument is also used to train undergraduate and graduate students in this basic tool. It enables hands-on citizen-science activities such as analysis of local water supplies and is made available to other researchers beyond the St. Louis University community. The proposal is aimed at enhancing research and education at all levels, especially by researchers at St. Louis university in areas such as: (a) prospective roles of inorganic cations in the origin of life, (b) the geochemistry of surface waters, shallow groundwaters, and soils, (c) ion-exchange in mineralized tissue with physiological pH regulation, (d) earth science to understand water transformations in the critical zone at the interface between water, air, soil and rock, (e) transport of sodium contamination from road salt, (f) wastewater contamination from sewer overflows using tracers, and (g) how mineralized tissues buffer perturbations to acid-base homeostasis in reptiles, amphibians and mammals.
