(a, b) Images of the electrochemical cell in position between the two ionization chambers and in front of the camera optics. (c) Iron distribution determined from the XAS edge jump measured at each binned pixel of the hyperspectral images for the two LFP electrodes investigated in the case study. A common color scale of the edge jump for both electrodes is given at the top. (d) Schematic of the FoV area (gray rectangle) over the area of the electrode (blue disk of diameter 6 mm).
