The fibTOF enables sensitive 3D chemical imaging with nanometer resolution

Add FIB-SIMS capabilities to commercial FIB-SEM microscopes for powerful secondary ion imaging and depth profiling

Advantages of the fibTOF

The fibTOF adds focused ion beam secondary ion mass spectrometry (FIB-SIMS) capabilities to FIB-SEM microscopes, enabling sensitive chemical imaging in three dimensions with nanometer resolution.

  • 3D chemical imaging of all elements with lateral resolution <50 nm and depth profiling resolution <10 nm
  • Sensitive detection of light elements such as hydrogen, boron, lithium and fluorine
  • Isotopic imaging for experiments to study transport, diffusion or reaction mechanisms
  • Unambiguous elemental identification with high mass resolving power
  • Compatible with major commercial FIB-SEM microscopes with no impact on image quality
