Microbeam Analysis - Electron Probe Microanalysis -
Methods for Elemental-Mapping Analysis Using
Wavelength Dispersive Spectroscopy
1 Scope
This Standard provides procedures for electron microprobe elemental mapping
analysis using wavelength dispersive spectrometry. The choice between mapping with
the electron beam moving digitally across the specimen (electron beam mapping) and
mapping with stage movement only (large-area mapping) is assessed. It describes five
types of data processing. the raw X-ray intensity data method, the k-value method, the
calibration method, the correlation method and the matrix correction method.
