Is a Ph. Eur. monograph the same as a BP monograph?

For substances covered by the European Pharmacopoeia, the BP reproduces the Ph. Eur. text, so the requirements are identical. The BP also contains national monographs that have no Ph. Eur. equivalent.

What are specified impurities in a Ph. Eur. monograph?

They are named impurities with individual limits, listed in the transparency statement of the monograph. Laboratories need reference materials for them to identify and quantify each one.

Does the COA need to state the Ph. Eur. supplement?

It should state the edition, and ideally the supplement, that applies. Monographs can change between supplements, and auditors check that testing followed the version in force.
