The list of available reference standards is regularly updated on the website of the EDQM (European Directorate for the Quality of Medicines & HealthCare). It comprises more than 3,000 substances, including chemical reference substances, herbal reference standards and biological reference preparations as well as reference spectra for the performance of tests and trials according to Ph. Eur. methods.
In addition, the EDQM summarises in tabular form on its website details of which reference substances have been replaced by new batches and which standards have been removed from the list of reference substances (since January 2023) or will be deleted in future (as of April or July 2023).
Information is also provided on changes to the packaging units of the standards, updates to the transport and storage conditions of the substances, and increases in the prices of some substances.
Finally, a description is given and additionally presented in a video on how to order reference substances.
The complete list of all currently available reference standards and the substances affected by this year's updates can be found on the EDQM website.
