Enhancement of an X-Ray Laboratory

化学系和地质系正在升级其 X射线衍射学领域的各自课程， 通过增加计算机控制和数据分析的光谱分析 系统到他们的X射线衍射仪，并通过替换 用于制备地质材料的废弃球磨机 使用X射线光谱仪进行定量分析。学生和 教师有能力：收集和存储X射线 衍射图案数字化为计算机文件， 可轻松访问、处理和分析;执行阶段 多晶材料的分析，使用最新的 JCPDS粉末衍射文件版本（电子版 媒体）和计算机化的搜索/匹配软件; 确定多相中不同相的百分比， 晶体材料;和制备地质材料， 定量化学分析，安静，无污染 制粉系统学生们正在获得宝贵的 使用计算机控制仪器的经验 用于数据收集和分析。

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.
