Live Online Training on 30 January 2024

The ECA organizes a Live Online Training on 30 January 2024. The participants will learn what aspects have changed and what is new in the revised Q2 guideline. Dr Joachim Ermer will further provide a critical discussion whether the gaps and uncertainties of the old guideline from 1994 have been sufficiently addressed, in particular considering the new USP General Information Chapter <1220> "Analytical Procedure Life Cycle".
