| The LEO
1530 is a high resolution field emission scanning electron microscope
(SEM), which together with an energy dispersive x-ray analysis (EDX system from
OXFORD2) provides the ability to visualise and
to analyse surface features of material as small as 0,3 microns in diameter.
This makes SEM / EDX a perfect system for the analysis of materials, minerals,
contaminant particles and particles collected by filtration. |
