Laboratory analysis of outermost surface layers

From surface analysis to outermost layer analysis

 Material’s surface is subject to numerous interactions with its environment and dictates the specific characteristics, performance of materials as well as providing protection from exterior constraints.

Surface analysis can help resolve many physicochemical problems:

  • As part of an expertise to determine the origin of a defect (corrosion, fissure, adhesive problem, unknown pollution…)
  • To optimize your production processes (surface treatment, machine calibration…) and improve the performance of your materials
  • To inspect the quality of the surface of your materials 

Outermost surface analysis : more specific chemical characterization

Complementary to surface analysis techniques (SEM, Optical microscopy…), techniques associated with outermost layer analysis used to collect specific data identifying chemical elements and molecules in a materials surface and its close environment.

They are used as part of multisectoral investigations such as :

  • Identification of the chemical nature of a pollutant or a contaminant which could cause cleanliness problems
  • Surface characterization (passivation and functionalization)
