Figure 6
Diffractograms of a copper oxalate powder collected at 17.5 keV with MYTHEN II and MYTHEN III. (a) Comparator threshold set at 12500 eV, in order to maximize the copper fluorescence background suppression. (b) Comparator threshold set at 8750 eV as in ideal conditions. The lower noise and improved threshold dispersion of MYTHEN III effectively suppress the copper fluorescence background, with less than 1 keV difference between the threshold and the energy of the fluorescence radiation.
