Scanning Electron Microscope (SEM)
Installed in 2008, our SEM has three detector systems. In secondary electron (SE) or backscattered electron imaging mode magnifications from approximately 20x to 300,000x are available. The energy dispersive X-ray detector (EDS) provides qualitative and semi-quantitative analysis of elements.
A wide range of sample types can be examined in our SEM. Samples can have a conductive coating applied to their surface, either sputtered gold or evaporated carbon, but this is not required. Samples must be dry (water is the main concern, but some oil-saturated samples might also be unsuitable, for example). Typical samples are thin section-size or materials < 1-cm diameter. Four 1-cm diameter samples can be loaded into the SEM simultaneously. Somewhat larger samples, up to a few cm on a side, can also be used, depending upon whether they fit through the airlock and pose no possibility of colliding with the detectors.
Scheduling Time on the SEM
