Electron Microprobe (EPMA)

野外和实验的输入数据，岩土材料的研究方向是矿物相的化学组成、矿物相的晶体结构和晶体取向。本文要求的用于分析轻元素（Be， B， C， N， O， F）的多层晶体电子探针将用于以下微观结构化学表征：高分辨率点和剖面分析，捕获主要，次要和痕量成分（高达~ 0.001 wt%）；高x射线光谱分辨率的微量元素分析在微到纳米尺度上的无损定量分析，特别是对有价值的样品，如钻样，陨石，空间任务或考古材料；分析薄层和极细粒度的材料；二维元素分布的扩散曲线及定量分析；对地质年代学和矿物组合压力和温度估计所必需的矿物进行定量分析；天然和合成玻璃的快速元素分析；生物矿化或地热样品中碳酸盐的微量元素分析。

The input data in both, field and experimental, geomaterial research directions are chemical compositions of mineral phases as well as the crystalline structure and crystallographic orientation of the mineral phases. The electron microprobe with multilayer crystals for analyses of light elements (Be, B, C, N, O, F), requested here, will be used for following microstructural chemical characterizations: High-resolution point and profile analyzes capturing major, minor and trace components (up to ~ 0.001 wt%); Trace element analysis with high X-ray spectral resolution; Non-destructive quantitative analysis on a micro- to nanometer scale, especially for valuable samples such as drill samples, meteorites, space missions or archaeological materials; Analysis of thin layers and extremely fine-grained materials; Diffusion profiles and quantification of two-dimensional element distributions; Quantitative analysis of minerals essential for geochronology and pressure and temperature estimates of mineral assemblages; Rapid elemental analysis of natural and synthetic glasses; Trace element analysis in carbonates from biomineralization or geothermal samples.
