Add the theoretical number of chemical states expected in your sample. For example, if analyzing a oxidized carbon surface, you might add three components: (~284.8 eV) C-O (~286.5 eV) C=O / O-C=O (~288.5 eV) 4. Establishing Constraints (Crucial Step)
Offers Shirley, Linear, and Polynomial background subtractions.
: To ensure a physically meaningful fit, the software allows users to fix or link parameters like peak position, area, and Full Width at Half Maximum (FWHM). xps peak fit 41 new download

Define the working region of your spectrum. Choose your background type (Shirley is the most common choice for transition metals; Linear works well for simple, flat baselines) and click optimize to subtract the background. Add the theoretical number of chemical states expected
