ThermoFisher Talos F200X

The Talos F200X G2 is a 200 kV FEG (Field Emission Gun) Analytical Scanning Transmission Electron Microscope (S/TEM). It is designed for fast, precise and quantitative characterization of functional materials, and it is ideal for in-situ and operando experiments.

  • The field emission electron source (X-FEG) delivers high density and high coherent electron beam.
  • The SuperX Energy Dispersive Spectrometry (SuperX EDS) system with the four Silicon Drift Detectors (SDD) that offers maximum collection efficiency with a solid angle of 0.9 srad, while being able to collect X-Rays at very high count rates.
  • The 4k x 4k Ceta 16M CMOS camera provides large field-of-view, fast (up to >30 fps full frame, >250 fps 512 x 512) imaging with high sensitivity and dynamic range.
  • Embedded Piezo-enhanced stage provides precise control of sample navigation and imaging stability for drift compensation.
  • Differential phase contrast (DPC) imaging can be utilized to image local electric and magnetic fields, and image light elements (low Z) at very low dose.
  • New software Velox provides advanced acquisition and analysis functionality for STEM and EDS data, on a 64 bit software platform.
  • The full remote-control of the system can reduce the environmental sensitivity.
  • An analytical platform for high resolution and in-situ dynamic observations: equipped with cooling stage, in-situ liquid/gas holders and 3D tomography holders.

  • Gatan 655 Dry Pumping Station for Cryo holders
  • Vitrobot sample preparation for Cryo-electron microscopy
  • An integrated RGA (residual gas analyzer) is now attached to the Protochips Atmosphere system. The RGA enables quantitative control and examination of nanoscale reactions within the gas cell holder, and allows for improved control over gas chemistries introduced to the sample environment.
  • Velox
  • Gatan DigitalMicrograph
  • S/TEM Tomography 4.x Data Acquisition Software
  • Inspect3D Xpress for Tomography reconstruction
  • Axon software integrates with the Talos to dramatically improve sample stability during in situ experiments. Axon tracks sample location and minimizes sample motion during sample heating, cooling, or when gasses or liquids are introduced in sample chamber.
