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.<\/p>\n
This document applies to inorganic particles larger than 100 nm and smaller than 100 \u00b5m in diameter.<\/p>\n
It applies only to analysis of \u201cgeneral\u201d powders, which means that it excludes procedures for special applications such as forensic or trace analysis.<\/p>\n
