The Departments of Chemistry and Geology are upgrading their respective curricula in the areas of x-ray diffractometry and spectrometry by adding a computerized control and data analysis system to their x-ray diffractometer, and by replacing an obsolete ball mill used to prepare geological materials for quantitative analysis using an x-ray spectrometer. Students and faculty have the capability of: collecting and storing x-ray diffraction patterns digitally as computer files where the data can be easily accessed, processed, and analyzed; doing phase analysis of polycrystalline materials using an up-to-date version of the JCPDS powder diffraction file (on electronic media) and computerized search/match software; quantitatively determining the percentages of different phases in multiphase, crystalline materials; and preparing geological materials for quantitative chemical analysis with a quiet, non-contaminating pulverizing system. Students are being provided with valuable experience in the use of computer-controlled instrumentation for data collection and analysis.

化学系和地质系正在改进它们各自在x射线衍射和光谱领域的课程，方法是在它们的x射线衍射仪上增加一个计算机控制和数据分析系统，并更换了一个过时的球磨机，该球磨机用于制备地质材料，以便使用x射线光谱仪进行定量分析。学生和教师具有以下能力：将x射线衍射图以数字方式收集和存储为计算机文件，使数据易于访问、处理和分析；使用最新版本的JCPDS粉末衍射文件（在电子媒体上）和计算机搜索/匹配软件对多晶材料进行相分析；定量测定多相结晶材料中不同相的百分比；用安静、无污染的粉碎系统制备地质材料进行定量化学分析。学生将获得使用计算机控制仪器进行数据收集和分析的宝贵经验。
