FEI Titan Transmission Electron Microscope (TEM)
Atomic-Scale Imaging and Nanoscale Compositional Analysis for Materials
Location: Jesser Hall room 158
The FEI Titan system allows for imaging of materials with atomic resolution in both the Transmission Electron Microscopy (TEM) and the Scanning TEM (STEM) modes. Compositional analysis is available using Energy Dispersive X-Ray Spectroscopy (EDX).
