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与所有相关的数据库相识别接口,并可额外使用晶体结构和补充的化学成分信息,例如基于x射线荧光的化学分析,用于获奖物种的齿状鉴定。
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数据库基础设施的日常工作,甚至在受控环境中,根据21 CFR第11部分的制药行业法规的要求。
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展示。
该聚类分析工具是对著名的多义词软件的改编。它有助于识别已知和未知的样本,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。

度量多维尺度是一种聚类分析数据的三维图形化表示方法。EVA还提供PCA图和最多6维图表,以可视化附加信息。
多扫描阅读器快速加载数百个扫描,并以二维表示形式提供了一个简单的概述。常规质量控制测量中的异常值很容易被发现,从倒数空间图或一系列非环境或操作数内测量中可以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,这有助于发现感兴趣的扫描进一步检查相转换,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、纹理不均匀或由于样品支架中的晶体排列而产生的首选取向的斑点)是通过利用大光束足迹和Bragg-Brentano几何的高分辨率结合使用LYNXEYE探测器系列的非对称1D检测实现的。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/匹配模块被普遍认为是最可靠和最精确的相位识别工具。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,许多改进进一步区分了EVA与传统的相分析软件
