Introduction

Electron Probe X-ray Micro Analyzer (EPMA or EMA) is abbreviated as electron probe. As a powerful analytical instrument developed based on the principles of electron optics and X-ray spectroscopy, it performs microscopic analysis of solid materials through the secondary electrons, backscattered electrons, X-rays and other signals generated by the electron beam acting on the micro area of the sample, including the analysis of the composition, morphology and structure of the micro area.
