Instrument Capabilities

The Rocky Mountain E-XPS facility is based on the unique capabilities of Scienta Omicron’s HiPP Lab system.  Here, we provide an overview of the instrument’s specifications and capabilities.

Source

The HiPP Lab from Scienta Omicron utilizes a high power, high energy resolution monocrhomated Al-Kα source with 600 W continuous operation and modified for near-ambient pressure XPS measurements.’

Analyzer

The energy analyzer boasts the following specifications:

  • Energy resolution < 15 meV FWHM at 20 eV pass energy and 500 eV kinetic energy
  • Pass energies of 20, 50, 100, 200, and 500 eV.

The analyzer can operate in standard transmission mode, or collect one-shot measurements to analyze spectra as a function of X-ray energy and either angle (angular mode) or lateral position (spatial mode).

  • Transmission mode kinetic energy range: 20 eV – 1500 eV
  • Angular mode kinetic energy range: 100 eV – 1500 eV. Parallel angular range: ± 9 degrees.
  • Spatial mode kinetic energy range: 20 eV – 1500 eV. Spatial resolution: < 10 μm

Sample Environment Conditions

  • Gas pressures of up to 30 mbar
  • Temperatures of up to 700 C.
  • Gas flow management system allows mixing of two separate feed gases, controlled via mass flow controllers, plus optional water vapor.
  • Chamber exhaust composition quantified and monitored via quadrupole mass spectrometer.
  • Optional electrical leads for operando biasing of samples.
