Scanning Electron Microscopy

The MTC houses a state-of-the-art scanning electron microscope (SEM) system that can conduct backscattered and secondary electron imaging. The system includes variable pressure capability to image non-conductive materials (concrete, rock, soils) and a field emission source that provides sub-nanometer imaging resolution. Features to conduct chemical analysis using X-ray microanalysis techniques are also available.
