Employing characterized beamlines as well as radiometrically calibrated detection systems in the Physikalisch‐Technische Bundesanstalt laboratory at the electron storage ring BESSY II in Berlin, fundamental parameters of the Zr (L subshells) and the Ti (K shell) have been experimentally determined and compared to available literature data. This study is mainly focused on the provision of a reliable uncertainty budget based on the calibrated instrumentation. Using a reference‐free X‐ray fluorescence approach and an advanced evaluation procedure without any input from databases, fundamental parameters, such as Coster–Kronig probabilities as well as fluorescence yields, are determined with both decreased and reliable uncertainties.
