The Advanced XPS Information Section is a collection of additional spectra, overlays of spectra, peak-fit advice, data collection guidance, material info,Ĭommon contaminants, degradation during analysis, auto-oxidation, gas capture study, valence band spectra, Auger spectra, and more. The Basic XPS Information Section provides fundamental XPS spectra, BE values, FWHM values, BE tables, overlays of key spectra, histograms and a table of XPS parameters.
