Electron Probe Microanalysis Back

Electron probe microanalysis (EPMA) is an analytical technique widely used for determining the elemental composition of solid specimens. It can produce maps showing the distribution of elements over the surface of a specimen while also accurately measuring their concentrations.

In combining two complementary techniques – wavelength-dispersive spectroscopy and energy-dispersive spectroscopy – in a single instrument known as a microprobe, EPMA produces a powerful analytical instrument. This has a wide range of applications, from studying the latest advanced solar cells to archaeological/geological material and metal alloys.

This clear, concise guide begins with a detailed explanation of the operation of the EPMA instrument and outlines the major steps in EPMA development. It also details various practical issues related to the instrument, describes potential problems that may arise and how to solve them.

In reading, researchers will be introduced to EPMA and understand its full capabilities.
