Actually my question is Regarding the Satellite region observed in the sample; Usually it is suggested that we have to cut it during the analysis or smoothed it during the data interpretation........But I did Xps analysis of mineral based sample(mainly contains iron Oxide)...................But in some paper(or my personal experience) it is suggested or observed that satellite peak or region shows a shift in its position, whenever oxidation state changes say for example Fe3+ to Fe2+. So, but is the proper or correct way for it, Whether we have to keep the satellite region or we have to cut it. Along with this, i need to know that (on the basis of observation) especially how we can finalize the splitting of 2p spectra of Fe peaks(GS spliting), whether Fe in 2p spectra will show three peaks or more than three peaks. Bcoz i did analysis of my sample in two instruments(One shows one peaks will split into 3 peaks or other shows peak will split into 4 peaks), hence both shows or supports different results(Remarks i used only Origin for my data interpretation on the basis of Binding energy value and fitting value). So i want to know the basic principle behind the deconvolution of peaks.....Bcoz, when ever we do the data interpretation through origin, we can easily manipulate or can do error. So, can somebody explain the general requisite of deconvulation, how can know whether data is properly analyzed or manipulated or contain the error in regard to deconvulation.
