X-RAY PHOTOELECTRON SPECTROSCOPY (XPS)

Service of X-ray photoelectron spectroscopy has the necessary equipment for the characterization of solid surfaces and dust. In the case of powder samples, pressing theses in the cases where it is possible to improve its usability.

You can choose different types of analysis:

• Record the overall spectrum and qualitative analysis of the surface composition.
• Detailed log of the components of the surface and semiquantitative analysis of its composition.
• Detailed log of the components of the surface, quantification and analysis of the oxidation states of these elements.
• Analysis of composition in function of depth by bombardment with Ar + ions. Qualitative analysis semiquantitative or quantitative analysis and oxidation states of elements in the different layers analyzed.
• Analysis of the surface composition as a function of angle of incidence of X-rays, which allows to know the composition of the outermost layers. Qualitative analysis semiquantitative or quantitative and analysis of oxidation states of elements of different measures depending on the angle of incidence.
