Iron | XPS Periodic Table | Thermo Fisher Scientific - US
Iron X-ray photoelectron spectra, iron electron configuration, and other elemental information. Experimental information. Fe2p overlaps strongly with Ni LMM Auger peaks, e.g., in some steel samples. Can use weaker Fe3p or Fe3s peaks instead for quantification. Some compounds/alloys of iron are magnetic. Degauss samples if possible before analysis.
