Stack of X-ray images spanning a small energy range across the L-absorption edge of calcium of a clay/humic substance dispersion. The lower left picture indicates the areas chosen for obtaining the spectrum at the lower right side. The image size is 20 µm × 20 µm, 100 × 100 pixels, taken with a dwell time per pixel of 6 ms. 40 images with an energy step size of ΔE = 0.25 eV have been taken for this image stack.
