Why It Matters 

Traditional XRD techniques fall short when crystals are too small or co-exist with complex phases. With TESCAN TENSOR, you can easily access complete structural information from nanoscale samples without compromise.

 

What You Gain with TESCAN TENSOR

  • Sub-Angstrom Resolution: Resolve atomic structure to sub-Angstrom resolution including hydrogen atoms

  • Improved diffraction patterns: Reduced dynamical scattering effects due to beam precession

  • Accurate Structure Refinement: Structure determination with R-factors as low as 8%

  • 4D-STEM Advantage: Diffraction data enhancement through smart diffraction averaging at each specimen tilt step.

  • Streamlined data processing: Data ready for structure refinements in PETS2 and JANA2020 software packages.

 

Proven on a Benchmark Standard 

In our case study with natrolite mineral, TENSOR achieved:

  • Solving the structure from a single 3D ED dataset

  • Determining the structure to 0.63 Å resolution at the R-factor as low as 7.9%

  • Determining the structure including hydrogens and visualization of their density
