Purdue University has a site license for CasaXPS allowing complete analysis XPS data. However, XPS data reqquire thorough analysis, and dedicated software is used for data analysis. XPS is widely used to determine the chemical composition of a surface (element concentrations, chemical states, lateral and depth distributions, etc.) Nowadays XPS has become a standard technique for the characterization of solid surface.
