Abstract
Lab managers and users of scanning electron microscope or electron probe microanalyzer facilities aiming for qualitative or quantitative X-ray analyses require comprehensive, yet flexible documentation structures for their daily work and available reference material, with a complete X-ray data library, a repository of energy- and wavelength-dispersive spectra, and an instrument scheduling mechanism. An online multilaboratory database system available at https://de-ma.ch is presented with the primary goals of providing information on microanalytical reference materials, analytical setups, characteristic X-ray data, and for managing reservation and training requests. This website is designed for multiuser facilities, where experience ranges from beginners to expert users. Registered users will find these tools useful in developing and maintaining high-quality, reproducible, and efficient analyses, whereas lab managers will keep records of their microanalytical reference material database and analytical protocols. The database also serves an educational purpose by (a) providing information on reference materials, (b) encouraging students to select appropriate X-ray lines to analyze, (c) providing analytical setups for point analysis or mapping, (d) identifying unknown X-ray lines, (e) displaying energy- or wavelength-dispersive spectra, and (f) recalculating mineral formula from quantitative wt% analysis results, based on a number of oxygen atoms or cations.
旨在进行定性或定量 X 射线分析的扫描电子显微镜或电子探针微分析设备的实验室管理人员和用户需要全面而灵活的文档结构来记录他们的日常工作和可用参考材料,包括完整的 X 射线数据图书馆、能量和波长色散光谱库以及仪器调度机制。https://de-ma.ch 上提供了一个在线多实验室数据库系统,其主要目标是提供有关微分析参考材料、分析设置、特征 X 射线数据的信息,以及管理预订和培训请求。该网站专为多用户设施而设计,用户经验从初学者到专家不等。注册用户会发现这些工具在开发和维护高质量、可重现和高效的分析方面非常有用,而实验室管理人员则会保存其微量分析参考材料数据库和分析协议的记录。该数据库还具有以下教育功能:(a) 提供有关参考材料的信息;(b) 鼓励学生选择适当的 X 射线进行分析;(c) 提供用于点分析或绘图的分析设置;(d) 识别未知的 X 射线;(e) 显示能量或波长色散光谱;(f) 根据氧原子或阳离子的数量,从重量百分比定量分析结果中重新计算矿物公式。
期刊介绍:
Microscopy and Microanalysis publishes original research papers in the fields of microscopy, imaging, and compositional analysis. This distinguished international forum is intended for microscopists in both biology and materials science. The journal provides significant articles that describe new and existing techniques and instrumentation, as well as the applications of these to the imaging and analysis of microstructure. Microscopy and Microanalysis also includes review articles, letters to the editor, and book reviews.
