Customised UHV system for investigating solid and powder catalysts via scanning XPS.

UHV System for Investigation of Solid & Powder Catalysts

This system is a customised multi-chamber UHV system for investigating solid and powder catalysts via scanning XPS.

Custom UHV System with Phi VersaProbe Scanning XPS Modules

Multichamber UHV system dedicated to surface analysis of solid and powder samples with a range of electron spectroscopy techniques:

• Ultraviolet Photoemission Spectroscopy (UPS)
• Auger Electron Spectroscopy (AES)
• Scanning Probe Microscopy (SPM)
• Low Energy Electron Diffraction (LEED)
• Temperature Programmed Desorption (TPD)

Custom UHV System with Phi VersaProbe Scanning XPS

The system is designed to allow a single sample holder type in all chambers.

  • spectroscopy chamber with analyser (incl. instrumentation and software) for XPS, UPS, AES, EPS and TPD techniques. The analyser enables XPS measurements with high resolution, precise depth profiling, chemical imaging and angular-resolved measurements
