Abstract | Energy dispersive (EDS) and wavelength dispersive (WDS) X-ray spectroscopy as electron probe microanalytical (EPMA) techniques, are for the determination of chemical composition of solid materials. EDS is suitable for fast qualitative and quantitative analysis. It has however limited sensitivity in quantitation. WDS quantitative analysis, with approprite reference standards, has better sensitivity and accuracy. WDS procedure is especially suitable for quantitative analysis of elements which overlap in the EDS spectra. In the case of low elemental concentraions in the samples, and for analysis of light elements. In general, quantitative analysis with both EDS and WDS is performed on the micro-level where the analyzed volume of the material is about 1 micro m3. Results of the analyses of selected lead glass samples, BaTiO3 - doped ceramics, and ALNICO magnets are presented and discussed. | |
