Two videos are used to explain first, why quantification by XPS of samples depends on the in-depth distribution of materials and second, how understanding the layer structure in a sample allows quantification to be performed. Quantification by Tags is used to combine information from survey and high resolution spectra thus providing insight into the composition for a thin film. Carbon 1s high resolution spectra are fitted using lineshapes from data. Lineshapes are computed using data measured from standard PVEE and PS polymers and applied to a thin film of PVEE on PS.
