The art of making matter speak... by XPS

The X-ray Photoelectron Spectroscopy (XPS) technique is an extreme surface analysis technique (probed depth varying from 3 to 10 nm) allowing to determine in a qualitative or quantitative way the chemical composition and the nature of the chemical forms of the elements present on the surface of a sample.

A multi-sectoral approach...

Analysis by XPS, why ?

The technique consists of irradiating the surface of a sample with an X-ray beam to then study the photoelectrons generated by the interaction between the beam and the material. Studying of photoelectrons makes it possible to determine the chemical composition of the material’s surface and to determine each element’s chemical environment (chemical bonds, oxidation number…).

Characterisation of elemental chemical composition

The X-ray Photoelectron Spectroscopy technique allows to determine several elements: 

  • determine the surface elemental chemical composition
  • determine the chemical environment to which each detected element belongs

A state-of-the-art technique to meet the different regulatory requirements of each sector: cosmetics, medical, food, pharmaceutical, etc.

Failure expertise

Failure can have several origins, which impact the reliability and performance of your product.

  • corrosion mechanism
  • presence of pollution
  • material wear
  • observation of discolouration
