Fortunately, such work is only rarely required. Concentrations versus XRF lines Useful to visualise the sample's composition at a glance. The plot shows if there would be any inconsistencies. For example, if Uranium, Thorium or Argon have not been calibrated, there Kappa values are not 'in line' with the Kappa's of their neighbours. Editing is for exclusion or inclusion of a standards in the regression analysis.
All plots are interactive.
Any change in a plot automatically updates the associated table. Spectral Impurities are taken into account, such as for those caused by the anode lines. Even absorption jumps and diffraction 'humps' are accounted for. It even solves the classical problem with Lanthanide ores and concentrates. This method is also referred to by the misnomer Fundamental Parameters.
