ElectronenMikrosonde
ElectronenMikrosonde, also known as an electron probe microanalyzer (EPMA), is an analytical tool used for the elemental and chemical characterization of solid materials. It utilizes a focused beam of high-energy electrons to interact with a sample. This interaction generates various signals, primarily characteristic X-rays, which are then detected and analyzed.
The principle of operation involves bombarding the sample surface with electrons from an electron gun. These
By analyzing the wavelengths or energies of the X-rays, the elemental composition of the sample can be
EPMA is a non-destructive technique, meaning the sample is generally not altered by the analysis. Its applications
