The Aerospace Institute's Electron Probe Microanalyzer (EPMA) officially begins operations—fully opening up external testing services.
2025-02-20
The Aerospace Institute has fully opened its external testing services, launching high-precision material characterization offerings.
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 installation and commissioning of an imported Japanese-made Electron Probe Microanalyzer (EPMA), which is now officially operational and fully open for external testing services.
As a company that proudly boasts two cutting-edge platforms—the Henan Province High-Performance Light Alloy Innovation Center and the Henan Province Aerospace Light Alloy Engineering Technology Center—this newly commissioned equipment will significantly enhance our firm’s independent R&D capabilities. It will also accelerate Henan Province’s transformation and upgrade of its traditional aluminum and magnesium manufacturing industries, paving the way for the development of a high-tech, high-value-added, and environmentally friendly alloy component manufacturing and advanced 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 efficient detection services—along with advanced material characterization—to businesses, 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 tightly controlled beam of electrons onto a sample’s surface, exciting the emission of characteristic X-rays that enable both qualitative and quantitative analysis of the sample’s elemental composition. It is currently the most precise instrument available for micro-area elemental quantification.
EPMA's analytical capabilities primarily focus on morphological observation and elemental analysis. Thanks to its high-energy electron beam, it 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, particularly for light elements and trace element detection, allowing for detailed qualitative and quantitative elemental analysis of specific microareas via techniques such as spot analysis, line analysis, and area analysis.
Compared to traditional scanning electron microscopy combined with energy-dispersive X-ray 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 mapping capability of SEM-EDS analysis.
More accurate quantitative analysis results: The EPMA uses a wavelength-dispersive spectrometer (WDS), which effectively separates overlapping peaks of characteristic X-rays, enabling more precise elemental quantification.
A more comprehensive elemental analysis range: EPMA can analyze all elements from Be to U, whereas SEM’s EDS spectroscopy faces significant limitations when detecting lighter elements such as Be, B, C, and others.
