FEI Tecnai F-20 TEM/STEM

The microscope is designed for both high resolution (Point resolution: 2.4Å) and analytical microscopy (energy resolution: 0.9eV). The microscope is equipped with: (1) Gatan DF/BF detector for STEM; (2) Gatan GIF 2001 system for EELS and EFTEM; (3) Oxford Instruments EDX detector for chemical information; (4) Gatan ultrascan CCD (2kx2k); (5) Oxford cryo- holder. It is ideal for micro and nano probe work including: HAADF STEM, nanodiffraction, spatially resolved EELS and EDS, HREM, EFTEM etc.
