It is sometimes necessary to have an accurate oxygen concentration that is free of any additional oxygen contribution from adventitious carbon species (such as when determining an oxygen:metal ratio). This calculator takes information from the survey and high resolution carbon 1s spectra and determines the amount of oxygen that is present from adventitious carbon species. This amount can then be deducted from the overall oxygen concentration.
