Kratos Photoelectron Spectrometer (XPS)
Facility Overview
The x-ray photoelectron spectrometer (XPS) was purchased from the Kratos Analytical Company. The spectrometer provides elemental and chemical state information on all types of sample surfaces from solid thin films, including dried powders.
This instrument is also equipped with the following surface analysis techniques:
- Ion Scattering Spectroscopy (ISS)
- Ultraviolet Photoelectron Spectroscopy (UPS)
- A delay-line detector for two-dimensional imaging in XPS mode
