Comparisons of oxidation states calculated using three different methods of analysis of µ-XRF maps and (a) µ-XANES linear regression (LR) and (b) linear combination fitting (LCF) of µ-XANES spectra. The dotted lines are regression lines for three chemical state maps, respectively. (c) Comparison of oxidation states estimated by µ-XANES linear regression (LR) and linear combination fitting (LCF) of µ-XANES spectra. |
