Charge Correcting to C 1s In CasaXPS

1. Fit the C 1s peak (see this post for fitting the C 1s to adventitious carbon), obtain the binding energy for the main peak (C-C, C-H).
2. Select all peaks to be charge corrected.
3. Under Options, select Processing - Calibration tab.
4. Enter measured C 1s (C-C, C-H) peak binding energy.
5. Enter true C 1s binding energy (usually 284.8 eV for most work, 285.0 eV for polymer work).
6. Select (click boxes for) Regions and Components.
7. Press Apply to Selection (for multiple spectra) or Apply (for a single spectrum only).
