diffrac.eva

diffrac.evaprovides 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 interfaces with all relevant databases for phase identification and may additionally use crystal structures and complementary chemical composition information from e.g. XRF based chemical analysis for its award-winning species dentification.

此外，fiffrac.eva支持源自当今快速检测器的大数据的有效评估，使用原位环境，高通量筛选或空间分辨的测量结果。该软件提供了特定的图表类型，还提供了用于聚类分析和基于图案匹配的晶体和无定形物种鉴定和定量的高级化学计量学工具。

It fully supports conventional file-based tasks but also integrates the DIFFRAC.SUITE database infrastructure for daily work, even in controlled environments as required by the 21 CFR Part 11 regulations for the pharmaceutical industry.

Finally, DIFFRAC.EVA 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.eva是获得测量第一印象的首选软件。一个重要的步骤是，从一个或几个稳定检测器的快照图像减少了数据，或者将像素从扫描2D检测器重新添加到常规的1维XRD数据中。EVA提供了良好的工具来进一步分析这些1D数据。从常规信号处理到扫描算术和更先进的技术，可以查看单个峰和完整的扫描。

The multi-scan reader quickly loads hundreds of scans and provides a simple overview in a two-dimensional representation. Outliers in regular quality control measurements are easily spotted and specific scans worth a detailed examination can be extracted from reciprocal space maps or series of non-ambient or in-operando measurements.

Supplementary scan information such as measurement position, temperature, humidity, charge states, or even intensity of an individual peak or the amount of amorphous background can be visualized in the side-view. Again, this assists in finding scans of interest for the further examination of phase transformations, the decomposition or formation of phases.

自首次发行以来，EVA的搜索/匹配模块通常被认为是相位识别的最可靠，最准确的工具。相应地，伊娃（Eva）在国际搜索比赛中表现最好（Le Meins等，2002，www.cristal.org/smrr）。从那时起

• Highly sophisticated residual search with respect to already identified phases, thus greatly improving analysis of minor phases
• 支持可变计数时间（VCT）和动态束优化（DBO）数据，以进行高度准确的痕量分析，这要归功于检测下限量显着降低（LLOD）
• Simultaneous search in multiple reference databases, such as the ICDD PDF2/PDF4+/PDF4 Minerals/PDF4 Organics databases
• 分组候选模式阶段，以处理相似或几乎相同参考数据库条目的越来越多的数量
• 识别阶段and accurate quantitative phase analysis based on RIR (reference intensity ratios) values

• 完整收集用于数据集成和评估的最佳算法
  
• 创新的设计和操作概念，以最大程度的简单性和灵活性。
• 它充分利用了现代计算机和操作系统，例如多线程，专用并行化，本机64位支持
• Real-Time-Preview of all evaluations for visual validation
• Reversing an action? No problem! EVA allows to undo and redo
• Highly flexible GUI adapts to the available user hardware, best operation practices and requirements of the various software modules
• Customization to user preferences for individual window layouts, column configurations and screen settings
• 与五件套件测量和结果管理器软件的高度集成
  
• An extensive step-by-step tutorial makes EVA easy to use from the very beginning.
