In the Pharmacopeial Forum, PF 50(1), a new version of USP Chapter <1053> Capillary Electrophoresis was published. The proposal is based on the version of the chapter official as of 01 August 2020.
According to the briefing notes, the following changes were made:
- "Add Hydrodynamic Injection and Electrokinetic Injection in the Apparatus section to elaborate these two injection modes.
- Add a new section for Adjustments of Operating Conditions for Capillary Electrophoresis.
- Reformat equations, improve wording, and conform to international terms throughout."
The reason for the changes is the harmonization with the corresponding chapter in the Japanese Pharmacopoeia and European Pharmacopoeia (please see our news archive for further information).
The draft of the revised USP chapter is available on PF Online. Comments can be submitted until 31 March 2024.
