摘要: 以贵州省高灰、高污染组分煤中矿物质的分析为例,应用Bruker AXS D8 Advance衍射仪测得煤中矿物相的X射线衍射图谱,分别应用数据分析系统EVA 12.0、X'Pert HighScore 2.0和MDI Jade 5.0对矿物物相组成的原始测试数据进行定性分析,通过对比分析过程和结果的差异比较了三款软件系统之间的异同和优劣.Abstract: X-ray Diffraction (XRD) is one of the most effective and commonest methods in crystal qualitative analysis. There are many factors affecting the analysis results, such as sample preparing, setting of the instrumental operating parameters. But the data analysis system is becoming the key factor in the modern instrumental analysis. There are three main software systems in XRD data analysis: EVA 12.0, X′Pert HighScore 2.0 and MDI Jade 5.0. In this paper, the advantages and the disadvantages of EVA 12.0, X′Pert HighScore 2.0 and MDI Jade 5.0 were studied and Evaluated. In this study the samples used in the analysis are high ash yield coals collected from Guizhou Province and Bruker AXS D8 Advance XRD instrument were used for XRD experiments. By comparing the analysis results, the similarities and differences as well as the advantages and disadvantages for these three softwares are evaluated.
