This document includes information on "Foreign Substance Analysis - Analysis of Foreign Substances Encapsulated in Inorganic Materials." Among foreign substance analyses, analyzing foreign substances encapsulated within materials requires advanced sample preparation techniques. We will introduce a case where microscopic foreign substances in inorganic materials were exposed and analyzed using EPMA (Electron Probe Micro Analyzer), along with details about the sample, analysis methods, and photographs. [Contents] ■ Overview ■ Sample and Analysis Methods ■ Analytical Techniques ■ Analysis Results *For more details, please refer to the PDF document or feel free to contact us.
