(a) Spectro-microscopy methodology for speciation analysis, based on acquiring multi-energy 2D fluorescence maps along the absorption edge of the target element. In this experiment 135 energies across the Zn K-edge were scanned. (b) XRF map (Zn Kα emission) collected above the Zn K-absorption edge (E = 9,669 eV). Scale bar length: 750 nm. The numbering on the colour scale bar represents fluorescence intensity (arbitrary units). (c) Cluster analysis representation revealing statistically similar regions according to their XANES spectra. Image reprinted (adapted) with permission from Gomez-Gonzalez et al. (2019BB13).
