Thermo Fisher Talos F200X G2 Scanning Transmission Electron Microscope
The scanning transmission electron microscope (S/TEM) with multiple energy dispersive spectrometers (EDS) and a High Angle Annular Dark Field (HAADF) detector is used to characterize materials on the nanoscale, enabling their exploitation in applications relevant to energy conversion/storage, catalysis, microelectronics/sensing, medicine, and metallurgy.
This instrument provides:
- Conventional TEM bright-field/dark-field imaging, electron diffraction, and high-resolution TEM imaging
- Z-contrast (HAADF) imaging capability at 0.16 nm resolution;
- Fast EDS elemental mapping
- Acquisition of tilt series with TEM/STEM/EDS capability and 3D reconstruction
- Alignments at both 200kV and 80kV for material and tissue samples, respectively
This instrument is both a user-based and fee-for-service instrument.
