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与所有相关数据库接口进行相识别,并且可以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,用于其获奖的物种识别。
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 Part 11法规所要求的受控环境中也是如此。
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呈现。
聚类分析工具是一个改编自著名的Polysnap软件。它协助鉴定已知和未知样品,分析混合物,异常值,并协助质量控制。它用于高通量筛选,但也用于分析非环境数据。

度量多维标度是一种在三维中以图形方式表示聚类分析数据的方法。EVA还提供PCA图和高达6维的图表,用于可视化附加信息。
多扫描阅读器可以快速加载数百个扫描,并以二维表示提供简单的概述。常规质量控制测量中的异常值很容易被发现,并且可以从互反空间图或一系列非环境或操作中的测量中提取值得详细检查的特定扫描。
补充扫描信息,如测量位置,温度,湿度,电荷状态,或甚至单个峰值的强度或无定形背景的量可以在侧视图中可视化。同样,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。
通过利用大光束足迹和Bragg-Brentano几何形状的高分辨率,结合使用LYNXEYE探测器系列的非对称1D检测,可以实现监测样品形态的简单方法(即由于样品支架中晶体的排列而导致的不均匀晶粒尺寸,质地或首选方向的斑点)。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,许多改进进一步将EVA与传统的相分析软件区分开来
