The present research deals with the FEG-EPMA mapping and Fe-Ti oxide mineral chemistry of Brahmaputra River sediments in Bangladesh. Major heavy minerals in the sediments consist of garnet (8.5-21.3%), kyanite (5.35-11.9%), monazite (2.3-5.3%), sillimanite (1.8-4.7%), zircon (3.6-9.1%),...
This new microprobe has a new SEM and EDS user interface (GUI) based on the FEG SEM's "SEM Center". It includes new algorithms for the auto functions of both the SEM column and the optical microscope. A new GUI provides a simplified work flow called "Easy EPMA" with built-in software...

Field emission gun electron probe microanalysis (FEG-EPMA) in conjunction with wavelength-dispersive X-ray spectrometry using a low acceleration voltage (Voce) allows elemental analysis with sub-micrometre lateral spatial resolution (SR). However, this degree of SR does not necessarily meet the ...
Measurements of the quantitative lateral analytical resolution at sputtered gold-layers with the FEG-EPMA JEOL JXA-8530FIn this paper we present measurements of the quantitative lateral analytical resolution of the field emission (FEG) electron microprobe JEOL JXA-8530F. In particular, the minimum ...

MEASUREMENTS OF THE QUANTITATIVE ANALYTICAL DEPTH RESOLUTION USING EVAPORATED METAL LAYERS WITH THE FEG-EPMA JEOL JXA-8530FThis work is a continuation of our systematic investigations of the spatial analytical resolution. So far, we studied the lateral analytical resolution whereby 'lateral' indicates ...
