Electron probe microanalyzer (EPMA) is used for the analysis of the chemical composition of the samples.

EPMA can detect very small element concentrations at the level as low as 100 ppm.  Microanalyzer can be used for example to produce element distribution maps from the surface of the samples.

Filament: LaB6
Five wavelength dispersive x-ray spectrometer (WDS)
