Funds from this Major Research Instrumentation (MRI) Program grant will support the acquisition and installation of a multicollector inductively-coupled plasma mass spectrometer (MC-ICP-MS) and laser ablation (LA) microprobe at the University of Missouri Research Reactor (MURR). The instrumentation will enable researchers at the University of Missouri (MU) to conduct high-precision studies on the subtle variations in isotopic composition present in natural and artificial materials caused by physical, chemical and biological processes. The intellectual merit of this project will be the availability of the new instrumentation to support a wide range of research activities at MU currently being conducted in the fields of social sciences, chemistry, geosciences, environmental sciences, life sciences and others. Some of the specific research topics to be supported will include: studies of human migration patterns, human behavioral evolution, transport of airborne pollutants, studies of melts and fluid inclusions in minerals, the role of volatiles in volcanic systems, petrogenesis of granites, climate evolution, searches for extremophilic microorganisms, and iron bioavailability in plants. Presence of this instrumentation at MU will open up additional areas of research with colleagues from other institutions who already collaborate with MU scientists. The broader impact of this instrumentation will be greater opportunities for undergraduate and graduate students to access the most modern and up to date elemental and isotopic analytical techniques. Students and faculty will have be able to design hands-on experiments not possible at another location, to receive training from one of the leading analytical laboratories in the nation, and to be trained on how to interpret the data acquired with the instrumentation. Presence of these new capabilities will attract more graduate students into the research programs at MU.

这项主要研究仪器（MRI）计划赠款的资金将支持在密苏里大学研究反应堆（MURR）的多策略耦合等离子体质谱仪（MC-ICP-MS）和激光消融（LA）微型Proprobe的获取和安装。该仪器将使密苏里大学（MU）的研究人员能够对由物理，化学和生物学过程引起的自然和人造材料中存在的同位素组合物的细微变化进行高精度研究。该项目的智力优点将是新工具的可用性，以支持当前正在社会科学，化学，地球科学，环境科学，生命科学等领域进行的MU广泛的研究活动。 一些要支持的具体研究主题将包括：人类移民模式的研究，人类行为进化，空气污染物的运输，矿物质中的融化和液体夹杂物的研究，挥发物在火山系统中的作用，花岗岩的石油发生，气候进化，搜索过度摩托微生物和过度摩托生物的植物和Iron Biobioavailsis和Iron Bioavailsibals和Iron Bioavailsibals in Cornterys in Cormabialiss in Cornterability in Corntoss in Corntoss。这种仪器在MU的存在将与已经与MU科学家合作的其他机构的同事开放其他研究领域。该仪器的更广泛影响将为本科生和研究生提供更多现代和最新的元素和同位素分析技术的机会。学生和教职员工将能够在另一个位置设计动手实验，从而接受美国领先的分析实验室之一的培训，并接受如何解释如何用仪器获得的数据进行培训。这些新功能的存在将吸引更多的研究生进入MU的研究计划。
