Meanwhile absolute concentrations rather than relative, instrument and setting specific values are requested as scientific standard in publishing provenancing results. Recent publications suggest that there is no reliable vendor software for elemental quantification of pottery with pXRF. It is unclear whether this is due to a lack of precision in the given trace element values of reference standards, or uncorrected matrix effects, or both. We faced similar problems when using >30 reference...
