X-Ray Photoelectron Spectroscopy (XPS / ESCA)

Strengths of the technique

  • Quantitative analysis of surfaces
  • Detection of all elements but H and He
  • Chemical state identification: binding and oxidation states
  • Applicable to different kind of sample systems like: papers, polymers, metalls, glasses, etc.
  • Preparation and analysis of sputter depth profiles
