What Does EPMA Stand For?

EPMA stands for Electron Probe Microanalysis

Electron Probe Microanalysis (EPMA) is a sophisticated analytical technique used to determine the elemental composition of materials at the microstructural level. Utilizing finely focused electron beams, EPMA enables high-resolution analysis by measuring characteristic X-rays emitted from the sample when it is irradiated. This method is widely applied in materials science, geology, and semiconductor research, providing valuable insights into the distribution and abundance of elements within a specimen. EPMA is noted for its precision, spatial resolution, and ability to analyze solid samples with minimal preparation.
