(a) A photograph of the mudstone rock sample mounted in the sample holder, with a scale bar. (b) The quartz–Pd off- and on-coincidence spectra, using the same CCD regions as shown in Fig. 3[link]. The on-coincidence spectra both with (source excitation 8 kV, 1.0 mA) and without (8 kV, 0.35 mA) the Rh foil in the incident beam are shown, illustrating especially the suppression of the K Kα fluorescence peak. The on-coincidence spectrum without the foil has been normalized to the Pd Lα1 and Pd Lβ1 peaks (i.e. the coincidence peaks) of the corresponding spectrum with the Rh foil.
