The results of the quantification are shown in a table at the bottom of the quantification section. Peak areas refer to properly fitted peaks for the elements listed. Starting the procedure will finally calculate the area of the selected peaks and add a quantification section to the browser. Further details can be added into the table or become visible as mouse-over information in the tooltip. Use a diagram to explain the origin of shake-up and shake-off peaks in an XPS spectrum. By default, only the peaks and the calculated atomic percentages are shown. Starting the procedure will finally calculate the area of the selected peaks and add a quantification section to the browser. Choose the peaks that you want to use for quantification either by selection of the spectra or the transitions of the element in the periodic table. Then you use the Identify Peaks button to automatically find and display excitations that match the peaks in the selected spectrum. A broad structure due to electrons from deeper in the solid which are ineslastically scattered (reduced KE) forms the background. Multiplet splitting (occurs when unfilled shells contain unpaired electrons). For the very first quantification of elements in an unknown sample the respective spectrum in the Plot View Data Browser is selected and the periodic table is activated. Sharp peaks due to photoelectrons created within the first few atomic layers (elastically scattered). Afterwards the quantification operation is performed on the group of selected spectra. In XPS, the intensity (IA) of a photoelectron peak from element A in a solid. As part of the quantification procedure, Prodigy’s ISQAR module automatically performs peak area operation on the selected peaks. Peak fitting analysis of the C1s peaks was done by using CasaXPS with Gaussian-Lorentzian peak shape models, as well as using the Ume-method predicting the contribution in percent of C atoms by fitting the C1s spectra with spectral components related to lipid, peptide (proteins and peptidoglycan) and polysaccharide (Ramstedt et al., 2011. The escape depth of the electron emitted from the atom, which depends upon. Each peak area is proportional to the number of atoms present in each element. By using templates and proven databases, the user gets an initial set of useful quantification results in only a few quick steps. X-ray photoelectron spectroscopy (XPS) is a surface characterization.
