Elemental Impurities

USP <232> and ICH Q3D came into force in January 2018, setting new standards for elemental impurities in drug substances, excipients, and drug products.

Although this guideline sets specifications for drug products only, the risk assessment approach also involves the determination of metallic impurities in APIs and excipients.

In this context, Quality Assistance offers consultancy for risk assessment and state-of-the-art expertise to perform the required analyses (including three generic ICP-MS methods for the determination of all EIs listed in Q3D).

Scientific Director at Quality Assistance Member of the EDQM Working Party that is in charge of the drafting and harmonisation of the monographs related to the implementation of the ICHQ3D guideline in the European Pharmacopoeia.

« Very early (2010), Quality Assistance has detected the high level of concern set by the first drafts of USP chapters <232> and <233> issued in the Pharmacopeial Forum 36 and later by the different steps of Q3D.

For 6 years, we have allocated resources to the development and validation of two generic methods which are efficient, rapid and ready-to-use.

Based on 35 years' experience in analytical services, the finalisation of this project means we are recognised as experts in the field. We are able to provide you with validated and robust methods necessary for risk assessment and design of control strategies ».
