Figure 4
XANES spectra of a Cu foil (used as reference) (top) and a NIST standard (oyster tissue, NIST #1566b) (bottom), measured in transmission mode and in fluorescence mode, respectively. The microbeam position was monitored by following the far-field image during the energy scan. No change in beam position was observed during the scans. |
