(Top) A line XANES example, showing the Cu K-edge line XANES of two powder reference samples on polyimide tape. (Bottom) Cu XANES traces extracted from the two highlighted regions labelled A (copper phosphate) and B (copper sulfide). Scan parameters: 95 energies, 7 mm wide transect, 10 µm pixel size, 10 ms dwell per pixel (1 mm s−1 scan velocity), 13.6 min total scan time. |
