一般扫描评估
常规数据和前沿研究
DIFFRAC。伊娃provides tools for the quick analysis of one- and two-dimensional diffraction data. It supports all Bruker detectors and XRD scan types. The EVA functionality covers a broad analytical spectrum from data reduction, basic scan evaluation and presentation, detailed peak analysis, phase identification and quantification, to the determination of crystallinity and crystallite size.
EVA与所有相关数据库相识别接口,还可以使用晶体结构和互补的化学成分信息,如基于XRF的化学分析,用于获奖物种识别。
此外,DIFFRAC。伊娃supports the efficient evaluation of big data that originate from today’s fast detectors, the use of in-situ environments, high-throughput screening or spatially resolved measurements. The software provides specific chart types, but also advanced chemometrics tools for cluster analysis and pattern-matching based crystalline and amorphous species identification and quantification.
它完全支持传统的基于文件的任务,但也集成了DIFFRAC。SUITE数据库基础设施用于日常工作,即使是在制药行业21 CFR Part 11法规要求的受控环境中。
最后,DIFFRAC。伊娃is used for the preparation of publication ready graphs and user specific reports, either directly in EVA or using the DIFFRAC.SUITE RESULTS-MANAGER and the instrument database.
DIFFRAC。伊娃is the software of choice to get a first impression of the measurement. An important step is the data reduction from one or several snapshot images of steady detectors or re-binning the pixels from a scanning 2D detector into conventional 1-dimensional XRD data. EVA provides the well-established tools to further analysis of those 1D data. This ranges from routine signal processing to scan arithmetics and more advanced techniques to look at individual peaks and complete scans.
EVA中的聚类分析提供了对大型x射线数据集更深入的理解和直观的展示。
聚类分析工具是由知名的polynap软件改编而来的。它帮助识别已知和未知的样品,分析混合物,异常值,并协助质量控制。它用于高周到筛选,但也用于分析非环境数据。

度量多维尺度缩放是一种图形化表示聚类分析数据的三维方法。EVA还提供了PCA图和多达6维的图表来可视化额外的信息。
多扫描阅读器快速加载数百个扫描,并提供一个简单的二维表示概述。在常规的质量控制测量中,异常值很容易被发现,并且可以从倒数空间图或一系列非环境或操作内测量中提取出值得详细检查的特定扫描。
辅助扫描信息,如测量位置、温度、湿度、电荷状态,甚至单个峰值的强度或非晶背景的数量,都可以在侧视图中可视化。再次,这有助于找到感兴趣的扫描,以进一步检查相变,相的分解或形成。
一种简单的监测样品形貌的方法(即由于晶粒尺寸不均匀而产生的斑点,通过利用大光束足迹和Bragg-Brentano几何结构的高分辨率,结合使用LYNXEYE探测器家族的非对称1D检测,实现了纹理或首选取向)。DIFFRAC。伊娃is used to visualize those data and to select individual scans for further detailed inspection.
自首次发布以来,EVA的搜索/匹配模块被普遍认为是最可靠和最准确的相位识别工具。相应地,EVA在国际搜索-匹配轮中表现最好(Le Meins等,2002,www.cristal.org/smrr).从那时起,许多改进使EVA进一步区别于传统的相分析软件
