WitrynaMeasuring elemental impurities in pharmaceutical materials is a well‑established application for Agilent ICP‑MS systems. Previous work (8) was performed using an earlier model of ICP‑MS and the elemental impurity limits published in the May 2011 draft of USP<232>/<233>, before the limits were harmonized with those published in ICH Q3D. WitrynaElemental impurities are traces of metals that can be found in finished drug products. The analysis of elemental impurities is necessary to describe the concentration of the trace elements in final drug products. Elemental impurities in pharmaceutical formulations can come from catalysts, formulation ingredients and process vessels.
