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
Scanning transmission electron microscopy (STEM) with imaging resolution 0.16 nm
X-ray energy spectrometer (EDS, with four embedded Bruker SDD detectors), for elemental chemical composition, elemental distribution mapping, and line profile element analyses using ChemiSTEM technology
EFTEM and EELS via a Tridiem GIF. Thickness maps, EFTEM maps and EELS spectra are a snap with Digital Micrograph - Microscope control integration.
High angle annular dark field detector (HAADF) with variable camera length for tunable contrast
Electron diffraction using selected area, micro-diffraction, and convergent-beam methods
Equipped for in-situ heating experiments up to 900°C
Cryogenic stage and transfer station for frozen specimen microscopy also supports the cryo ultramicrotome we have in house.
Integrated 3D Tomography image reconstruction using in house Avizo
Image capture via UltraScan 1000XP model 994 digital camera
