Casaxps license4/14/2023 ![]() The University of Iowa purchased a site license for data processing software, CasaXPS by Neal Fairley. Other applications include fast parallel elemental, Auger and secondary election imaging, Auger spectroscopy, and UPS spectroscopy.Non-destructive depth profiling using resolved XPS.Presence of trace elements, mineral, etc.Elemental information from thin layers (sections).Characterization catalysis products and intermediates.Characterization of surface components on catalyst.Bonding information, presence of catalysts traces, etc.Functional groups according to the chemical shift.Parallel imaging of chemical state (Si vs SiO2).Resulting spectrum is obtained from the sample layers within ~3 nm in depth thus giving great surface sensitivity. ![]() Emitted photoelectrons are being analyzed by energy in the analyzer and plotted as a function of binding energy. Soft x-rays are used to probe the outer layers of the sample.
