The Aerospace Institute's Electron Probe Microanalyzer (EPMA) officially begins operations—now offering external analysis services.
2025-11-04
The Aerospace Institute opens up external inspections and launches high-precision material characterization services.
Recently, the headquarters of Zhengzhou Light Alloy Technology Research Institute Co., Ltd. in the High-Tech Zone (hereafter referred to as the Aerospace Institute) has completed the commissioning of its Japan-imported Electron Probe Microanalyzer (EPMA), which is now officially operational and open for external inspection services.
As a company that proudly hosts two major platforms—the Henan Provincial High-Performance Light Alloy Innovation Center and the Henan Provincial Aerospace Light Alloy Engineering Technology Center—this newly operational equipment will significantly enhance our firm’s independent R&D capabilities. It will also accelerate the transformation and upgrading of Henan’s traditional aluminum and magnesium manufacturing industries, propelling them toward a high-tech, high-value-added, and environmentally friendly future in the advanced alloy components manufacturing and precision processing sector.
Meanwhile, the introduction of this equipment marks a new milestone for the company in the field of micro-area compositional analysis, enabling it to provide precise and reliable compositional analysis and materials characterization services to enterprises, universities, and research institutions across industries such as aerospace, new energy, electronic devices, and geological resources.

High-End Precision Instruments: Advantages of the Electron Probe Microanalyzer
Electron Probe Microanalysis (EPMA) involves focusing a fine electron beam onto the sample surface to excite characteristic X-rays, enabling both qualitative and quantitative analysis of the sample's elemental composition. It is currently the leading instrument for micro-area elemental quantification.
EPMA Function and Operating Principle
EPMA's analytical capabilities primarily focus on morphological observation and elemental analysis. Thanks to its high-energy electron beam, EPMA enables highly precise morphological imaging at the micrometer scale, clearly revealing surface features of samples through secondary electron imaging, backscattered electron imaging, and absorbed electron imaging modes. Additionally, EPMA excels in high-precision quantitative analysis, as well as in the analysis of light and trace elements. It allows for qualitative and quantitative elemental analysis of microregions via techniques such as spot analysis, line analysis, and area analysis.
Compared to traditional scanning electron microscopy combined with energy-dispersive spectroscopy (SEM+EDS), EPMA offers the following significant advantages in elemental analysis:
Higher elemental detection sensitivity: EPMA can detect elements at ppm levels, significantly surpassing the elemental analysis capabilities of SEM's EDS spectroscopy.
More accurate quantitative analysis results: The EPMA uses a wavelength-dispersive spectrometer (WDS), which effectively distinguishes overlapping peaks of characteristic X-rays, enabling more precise elemental quantification.
Elemental analysis range: EPMA can analyze all elements from Be to U, whereas SEM-EDS energy-dispersive spectroscopy has significant limitations when examining lighter elements such as Be, B, and C.
