FEI Titan 80-200 TEM/STEM with ChemiSTEM Capability
The OSU Titan TEM with ChemiSTEM capability. The Titan is now regularly used to generate high quality STEM EDS maps using its four Bruker SDD detectors. It also has recently been used to generate published Tomograms of nanomaterials for internal OSU customers. In addition, the accelerating voltage can be reduced to 80 keV for enhanced contrast on lower molecular weight samples from Biology and or Graphene.
Field emission electron source, XFEG for high brightness and stability compared with Tecnai.
Triple Lens that enables variable convergence angle on the multifunction knobs for fine tuning CBED and or EELS data.
0.24 nm TEM image resolution; information limit 0.11 nm
