X-ray Photoelectron Spectroscopy XPS

Surface analysis is a mandatory element in the study of new materials and modified components. Structural analysis and morphology provide many answers to technological productions and researchers.

Thermo Scientific offers X-ray photoelectron spectrometers for surface analysis. These innovative products make it possible to analyze the surface structure and track surface interactions. Modern technologies require knowledge in the field of ultra-thin films and nanostructures. It is surface analyzers that are widely used for the development of nanotechnologies, which are the basis of scientific development and progress.

The surface of materials is largely determined by their interaction with the environment and / or other materials. Surface analyzers provide information on the chemical and physical interactions that occur on the surface of materials and / or their surface lamellae. The surface is affected by factors such as corrosion, catalytic processes, moisture, various types of radiation and interference and others and all these changes can be tracked and controlled. This enables researchers and manufacturers to improve and / or protect a material.

X-ray photoelectron spectroscopy is also known as electron spectroscopy. In that reason we can have elemental composition, the empirical formula, the chemical composition and the structure of the materials, determined with its help.

Spectra are obtained as a result of X-ray irradiation and together with this the kinetic energy of the electrons emitted in the upper layer is measured in the range 1-10 nm of the material under study. The energies and intensities of the photoelectron peaks allow qualitative and quantitative analysis of any surface element without hydrogen.

Thermo Scientific offers three basic surface analysis devices.

• ESCALAB QXi X-ray Photoelectron Spectrometer Microprobe;
• Nexsa G2 Surface Analysis System;
• K-Alpha X-ray Photoelectron Spectrometer System.

Surface analyzers can be used for a variety of materials and applications, such as semiconductors, microelectronics, films, polymers, shells, catalysts, lubricants, cleaning materials, oxidants, corrosion, fibers, automotive, aviation, and more.
