Surface Analysis

Analyse the chemical composition of surface layers

WHAT IS SURFACE ANALYSIS?

The surface composition affects a material's properties and influences its eventual use and performance. Analysing the chemical composition at the surface and interface layers provides critical information on product surface quality, contamination, reaction and stability.

TÜV SÜD provides comprehensive surface analysis services to help various industries such as semiconductor, microelectronics, advanced materials, polymer products manufacturing determine the product performance and process conditions. Specialised instruments such as the X-ray Photoelectron Spectroscopy (XPS), Auger Electron Spectroscopy (AES) are employed to help obtain the composition of a surface by analyzing the photoelectrons that are emitted.
