Introduction to Electron Microprobe Analysis and Quantitative Microanalysis

To analyze geological, planetary, and materials science samples at the micrometer scale, researchers rely on the powerful capabilities of electron microprobe analysis. This course provides a thorough, text-based introduction to the foundational theory and practical principles of quantitative microanalysis. You will start by mastering key terminology, basic concepts of electron-specimen interactions, and foundational definitions before exploring advanced analytical techniques. By working through this comprehensive text-only guide, you will develop the theoretical knowledge required to configure analytical runs, interpret spectral data, and evaluate raw measurements into high-quality chemical datasets. What you'll learn: - Understand the physics of electron beam interactions with solid materials and how characteristic X-rays are generated - Compare wavelength dispersive spectrometry (WDS) and energy dispersive spectrometry (EDS) for optimal analytical setup - Master the ZAF matrix correction procedures to transform raw X-ray intensities into accurate weight percentages - Interpret scanning electron imaging modes including back-scattered electron (BSE), secondary electron (SE), and cathodoluminescence (CL) - Configure elemental mapping parameters to visualize chemical zoning and phase distribution - Apply modern data validation techniques and standard calibration workflows to ensure analytical precision The course begins with fundamental electron-matter interactions, moves through the mechanics of spectrometers, and concludes with data correction procedures and imaging strategies. It is designed for beginners, students, and researchers in earth sciences and materials chemistry who have no prior experience with microprobe instrumentation. Start your journey into microanalysis and learn to decode the chemical secrets of solid materials.
