We used to order a Reference Standard from the EDQM, but it is no longer in the on-line catalogue. Can you provide it? (Copy)

The EDQM supplies the reference standards that are necessary for the prevailing tests and assays of the Ph. Eur. Please verify that the reference standard is still needed for the monograph in force. Following a revision of a monograph, it may happen that a reference standard is no longer necessary for the tests and assays of the latest version of the monograph.
