Scanning Electron Microscopy (SEM) @ University of Limerick (UL) MSSI

Institution University of Limerick (UL) MSSI
County Limerick
Technique Category Image Analysis / Microscopy
Technique Scanning Electron Microscopy (SEM)

Basic Capabilities

Microscopy: observation of Micron to submicron particles. Elemental composition (C, O, F, etc_ qualitative not quantitative). Backscattered imaging for atomic weight contrast. Diffraction of metals/ceramics.

Equipment

Equipment Make Hitachi
Equipment Model SU-70

Advantages/Limitations

Advantage of Technique/Equipment Site selective compositional analysis. Only needs small amount of material (tip of microspatula). Top magnification of 800 Kx and 1 nm resolution. Voltages from 0.1-30kV
Limitations of Technique/Equipment Material needs to be vacuum compatible. Material needs to be stable under the beam. Sample can charge so low voltages or coatings may need to apply to some samples. Sample must be dry.

Other Details

Containment None. If sample is volatile, it is unsuitable for vacuum.
