The investigation of an ancient Chinese ceramic served to further develop and validate fundamental parameter‐based quantitation procedures in reference‐free x‐ray fluorescence (XRF) analysis. The XRF measurements of this sample were performed at the four‐crystal monochromator beamline of the Physikalisch‐Technische Bundesanstalt (PTB) at the BESSY II synchrotron radiation facility employing different excitation energies. The parallel processing of the XRF spectra recorded at different excitation energies provides a means to simultaneously evaluate relevant fundamental parameters and secondary enhancement processes such as those induced by photoelectrons. Employing well‐characterized and absolutely calibrated instrumentation, all experimental parameters involved in XRF are known for small relative uncertainties allowing for a completely reference‐free quantitation. Apart from traces of rare earth elements, the analytical results of the Chinese ceramic achieved by reference‐free XRF are in line with target values given within a proficiency test of the International Atomic Energy Agency (IAEA) involving atomic and nuclear methods.
