The EDQM has announced that the harmonised general chapter Chromatography was signed-off by the Pharmacopoeial Discussion Group (PDG), which brings together the European Pharmacopoeia (Ph. Eur.), Japanese Pharmacopoeia (JP) and the United States Pharmacopeia (USP).
Harmonised Requirements
In a press release dated 08 November 2021, the EDQM states that during the harmonisation of the text, particular attention was paid to the following aspects:
- Terminology, definitions and interpretation of chromatograms
- System suitability
- Adjustment of chromatographic conditions
- Quantitation procedures
The approach goes back to joint PDG–industry meeting in 2009, on which the PDG was encouraged to add harmonisation of the three regional chapters on chromatography to the PDG work programme.
The corresponding regional texts are scheduled for publication according to the following dates:
- Ph. Eur.: July 2022
- JP: December 2022
- USP: December 2022
