This Major Research Instrumentation award provides for the acquisition of geochemical instrumentation which will serve faculty and undergraduate student needs within the Claremont University Consortium (CUC), providing rapid and cost-efficient instrumentation to analyze chemical composition in a wide range of rock, soil, sediment, seawater, and biological materials. This instrumentation will substantially accelerate activities within the research programs of faculty as well as foster interdisciplinary collaboration. The ICP-OES will expand the analytical facilities of the Environmental Science, Biology, Chemistry, and Geology programs and will strengthen collaborative teaching and research among the students and faculty in diverse disciplines from separate institutions. Acquisition of the instrumentation will directly serve a diverse group of undergraduate STEM and non-science majors through integrated lab work in courses and individual student research training. In-house instrumentation will greatly enhance students? ability to directly and clearly connect first-hand scientific training and research to real-world concerns with scientific, environmental, and/or social benefits. The instrument will be housed at the W.M. Keck Science Department of Claremont McKenna, Pitzer, and Scripps Colleges, and faculty at each of the five Claremont Colleges (including Harvey Mudd and Pomona) will use the complete analytical system to train an economically and socially diverse group of STEM and non-science undergraduates on analytical instrumentation, data acquisition, processing, and interpretation. Training in geochemical analysis will help foster success for graduates who go on to work in industry or conduct graduate research.Specifically, this award funds the acquisition of an Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) instrument, coupled to a laser ablation (LA) inlet system and microwave digester. The LA-ICP-OES and microwave digester will allow researchers to generate paleo-reconstructions of seawater temperature and elemental cycling from the skeletons of long-lived organisms to understand variability within our climate and ocean systems, trace the progression of ancient mining and human movements with trace element time series derived from speleothems and fossil teeth, constrain the compositional suitability of barite in soils for Ar/Ar geochronology to help generate a new partial chronology for Pliocene-Holocene climate records in the desert Southwest, analyze feldspar and hornblende to unravel crystal growth stages and mineral responses to changing magmatic and metamorphic conditions and in analyses to understand cycling of nutrients during the Cambrian explosion. Additional users will also incorporate analyses by ICP-OES into their research and teaching programs. Academically, the instrumentation will be used to measure soil chemical compositions in the core course required of all non-science environmental analysis majors and minors at Claremont, and in an upper division soil science course. Senior thesis students and upper level science students at all five CUC colleges will use the instrumentation to measure heavy metals in a variety of materials to determine product origins and interpret potential consumer health impacts. Similarly, the instrumentation will support a pilot group-thesis project to measure suspended sediments in rivers in Costa Rica. Thus, this ICP-OES will provide hands-on undergraduate training through both structured laboratory activities and original student-faculty research.

这项重大的研究仪器奖提供了获得地球化学仪器的获取，该仪器将在克莱蒙特大学财团（CUC）中为教师和本科生需求提供服务，提供快速且具有成本效益的仪器，以分析各种岩石，土壤，沉积物，海水，海水和生物材料的化学组成。该仪器将在教师研究计划中大大加速活动，并促进跨学科合作。 ICP-OES将扩大环境科学，生物学，化学和地质计划的分析设施，并将加强来自不同机构的不同学科的学生和教师之间的协作教学和研究。获取仪器将通过课程和个人研究培训的综合实验室工作直接为各种各样的本科茎和非科学专业提供服务。内部仪器会大大增强学生吗？能够直接，清晰地将第一手科学培训和研究与科学，环境和/或社会利益联系起来的现实关注。该乐器将安置在W.M.克莱蒙特·麦肯纳（Claremont McKenna），皮策（Pitzer）和斯克里普斯（Scripps）学院的凯克科学系（Keck Science Science）以及五所克莱尔蒙特学院（包括哈维·穆德（Harvey Mudd）和波莫纳（Pomona）在内的五所学院的教师）将使用完整的分析系统来培训经济和社会上多样化的STEM和非科学本科生在分析仪器，数据收购，处理，加工和解释方面进行的。地球化学分析中的培训将有助于为继续从事行业或从事研究生研究的毕业生促进成功。特别是，该奖项为收购电感耦合的血浆光学发射光谱（ICP-OES）仪器的收购提供了资金，并与激光消融（LA）Inlet System和Microwave Digester相连。 The LA-ICP-OES and microwave digester will allow researchers to generate paleo-reconstructions of seawater temperature and elemental cycling from the skeletons of long-lived organisms to understand variability within our climate and ocean systems, trace the progression of ancient mining and human movements with trace element time series derived from speleothems and fossil teeth, constrain the compositional suitability of barite in soils for Ar/Ar geochronology to help在沙漠西南部，为上新世气候记录产生了新的部分年表，分析了长石和角闪闪发光，以阐明晶体生长阶段，以及对改变岩浆和变质状况的矿物质的反应，以及在分析的分析中，以了解剑术爆炸期间营养物质的循环。其他用户还将将ICP-OES的分析纳入其研究和教学计划中。从学术上讲，该仪器将用于测量所有非科学环境分析专业的核心课程中的土壤化学成分，以及在克莱蒙特（Clemont）的未成年人以及上层的土壤科学课程中。所有五所CUC学院的高级论文学生和高级科学专业的学生将使用该仪器来测量各种材料中的重金属，以确定产品起源并解释潜在的消费者健康影响。同样，该仪器将支持一个试点小组论文项目，以测量哥斯达黎加河流中的悬浮沉积物。因此，该ICP-OE将通过结构化的实验室活动和原始的学生教师研究来提供动手的本科培训。
