X-Ray Photoelectron Spectroscopy (XPS)

Research and Demonstration Laboratory
Polymer Institute, SAS
in cooperation with Thermo Fisher Scientific

In XPS we are concerned with a special form of photoemission, i.e., the ejection of an electron from a core level by an X-ray photon of energy hv. The energy of the emitted photoelectrons is then analysed by the electron spectrometer and the data presented as a graph of intensity (usually expressed as counts or counts/s) versus electron energy – the Xray induced photoelectron spectrum. XPS is a surface sensitive technique, since the depth from which information can be derived is a few nanometers (2-10 nm) [J. F. Watts, J. Wolstenholme. An introduction to surface analysis by XPS and AES, Wiley 2003].


Our laboratory is offering surface analysis of solid samples (plates, films, powders) of the size up to 60 x 60 x 20 mm (width x length x height).
