I need to calculate the N/C molar ratio from my XPS data of two polymers. I need to confirm whether the calculation is carried out using data from Survey spectra or High-resolution spectra of N 1s and C 1s respectively.
From a paper I am following they calculated this ratio N/C by measuring the relative atomic compositions. Are they referring to the atomic compositions obtained from Survey spectra or High-resolution spectra of N 1s and C 1s respectively? Unfortunately, the paper only shows the "Functional Group Percentage Values' obtained by peak fitting of C 1s, N 1s and O 1s.
Thank you!
