Each element has a unique set of electronic states | |||
Each element give a specific "finger-print" in the XPS spectrum. The binding energy of the electrons in atoms are different for all elements, and when measuring a photoelectron spectrum over a wide range of energies, the main line from each element will be placed at a specific energy in the spectrum. | Each element give a specific "finger-print" in the XPS spectrum.
