  • "Apparatus: a description of the two modes of injection, the hydrodynamic injection and the electrokinetic injection, has been added.
  • Adjustments of operating conditions: the section has been introduced to list the parameters that may be adjusted to satisfy the system suitability criteria.
  • In addition, the chapter has undergone a general review and minor and/or editorial changes have been made throughout the text in order to clarify some parts."

The full text of the proposed revised chapter and further details on the revision and can be found, after registration, on the Pharmeuropa website.
