ESCA XPS

Photoelectron spectroscope with X-ray monochromator, argon ion gun for surface cleaning and low energy electron gun to compensate for electric charge.

USES OF THE EQUIPMENT

  • Analysis of the contributions of different chemical states of the same element (for examples oxidation versus metal components)
  • Studies of problems originating from design and production processes (such as surface contamination) in, for example, paints, chemical products, pharmaceuticals, wiring, metal coatings and dental implants
  • Profilometric studies of materials with multi-layered structures (up to a maximum of 0.3 micrometres).

TECHNICAL SPECIFICATIONS

PHI 5500 Multitechnique System (from Physical Electronics) with a monochromatic X-ray source (Al K line of 1486.6 eV energy and 350 W), placed perpendicular to the analyzer axis.
