Industrial Problem Solving Using Surface Analysis Techniques

Surface analysis is the study of the chemical composition and/or physical structure of the outer regions of solid samples.  Surface composition is important in many chemical processes involving the interaction between surfaces and their environment, or between two surfaces.  Examples include oxidation, corrosion, wear, catalysis, adhesion and bonding. 

Two of the most popular surface analytical techniques are XPS and AES, which are forms of electron spectroscopy.   

This presentation will provide a basic review of these techniques and the information they supply, along with current applications and case studies from the use of XPS and AES in an industrial laboratory.
