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可与所有相关数据库进行相识别,并可额外使用晶体结构和互补的化学成分信息,例如基于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。用于日常工作的SUITE数据库基础设施,即使在制药行业21 CFR第11部分规定所要求的受控环境中。
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中的聚类分析为大型x射线数据集提供了更深入的理解和直观的呈现。
聚类分析工具是由知名的polynap软件改编而来。它有助于识别已知和未知样本,分析混合物,异常值,并有助于质量控制。它用于高通量筛选,也用于分析非环境数据。

度量多维缩放是聚类分析数据的一种三维图形化表示方法。EVA还提供PCA图和最多6维的图表,以可视化其他信息。
多扫描阅读器快速加载数百个扫描,并提供二维表示的简单概述。常规质量控制测量中的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中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无定形背景的数量,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进一步检查相变,分解或形成的相。
通过利用大束流足迹和Bragg-Brentano几何的高分辨率,结合使用LYNXEYE探测器系列的不对称1D检测,实现了监测样品形态的简单方法(即由于样品支架中的晶体对齐而导致的不均匀晶粒尺寸、纹理或优选方向)。DIFFRAC。伊娃is used to visualize those data and to select individual scans for further detailed inspection.
自第一次发布以来,EVA的搜索/匹配模块通常被认为是最可靠和最准确的相位识别工具。相应地,EVA在国际搜索匹配循环赛中表现最好(Le Meins et al., 2002,www.cristal.org/smrr).从那时起,大量的改进进一步将EVA与传统的相分析软件区分开来
