This project is purchasing a computer-controlled ion chromatograph and autosampler for the analysis of common inorganic anions, organic acids, and cations; an aluminum oxide ring mill vessel for rapidly crushing small, fine-grained rock and soil samples; and a powder diffraction database, CD-ROM computer, and x-ray diffraction (XRD) control and database search software to enhance the current XRD instrument. The new equipment is enhancing sample preparation and chemical analyses of natural water, rocks, soils, and other environmental samples. This enhancement is driven by ongoing efforts, in the Department of Geology, Civil Engineering, Chemistry, and Biology, to replace abstract laboratory exercises with those that cover similar concepts but involve hands-on sample collection, preparation, and analysis. The object, in addition to teaching the skills and concepts, is to give introductory and advanced students a better understanding of the nature of science and the purpose of analytical research and measurement. *

该项目将购买一台计算机控制的离子色谱仪和自动进样器，用于分析常见的无机阴离子、有机酸和阳离子;一台氧化铝环磨机，用于快速粉碎小颗粒岩石和土壤样品;一个粉末衍射数据库、光盘计算机和X射线衍射控制和数据库搜索软件，以增强现有的X射线衍射仪器。新设备正在加强天然水、岩石、土壤和其他环境样品的样品制备和化学分析。这种增强是由地质学，土木工程，化学和生物学系正在进行的努力所推动的，以取代抽象的实验室练习，这些练习涵盖了类似的概念，但涉及动手样本收集，制备和分析。除了教授技能和概念外，目的是让入门和高级学生更好地理解科学的本质以及分析研究和测量的目的。 *
