中文名称：微束分析 用WDS和EDS分析一般粉末的试样制备方法
英文名称：Microbeam analysis — Methods of specimen preparation for analysis of general powders using WDS and EDS
发布日期：2018-10
标准范围
This document specifies specimen preparation methods for the analysis of particles in powders using
energy-dispersive spectrometers (EDS) or wavelength-dispersive spectrometers (WDS) installed on
an EPMA or SEM. The preparation methods for powder particle analysis are classified by the analytical
purpose and the particle size.
This document applies to inorganic particles larger than 100 nm and smaller than 100 µm in diameter.
It applies only to analysis of “general” powders, which means that it excludes procedures for special
applications such as forensic or trace analysis.
