Dr Joachim Ermer, Ermer Quality Consulting, Germany


Besides regulatory expectations, in particular the new ones in Q2(R2), this Live Online Training provides practical recommendations and orientation for demonstration of the on-going suitability of analytical procedures. A rational and efficient validation approach is ultimately based on the respective routine application, which should be reflected in the validation design. This includes the identification of the relevant performance parameters, the selection of appropriate tests and calculations and, in particular, the establishment of acceptance criteria for the evaluation.

Both trainings focus on the relevant performance characteristics, taking the - long-awaited - revision of the ICH Q2 guideline as well as the new Q14 guideline Analytical Procedure Development from November 2023 into consideration. Lifecycle aspects will be included in the discussion.


According to EU GMP Guide Part 1, Chapter 6, Quality Control (6.15) and US 21 CFR 211.194, analytical procedures must be suitable for their intended purpose. The regulatory requirements to validation of analytical procedures utilised for release and stability studies of drug substances and drug products are described in the ICH guideline Q2(R2). However, its degree of detail is rather low, and the examples provided in Annex 2 often lack orientation beyond the guideline text. The lifecycle aspect of validation is treated in Q2(R2) rather as the “poor stepchild”, but covered better in the new ICH Guideline Q14 Analytical Procedure Development, and – in a true holistic way - in the USP General Information Chapter <1220> The Analytical Procedure Lifecycle.

Target Group

These Live Online Training Courses are aimed at executives and employees from Quality Control, Quality Assurance, and regulatory who want to gain a better understanding of the GMP requirements for validation of analytical procedures, in particular the new aspects and requirements of the revised ICH guideline Q2(R2), and who are interested in practical recommendations for an efficient design, execution, and evaluation of a successful analytical validation.

Technical Requirements

We use Webex for our live online training courses and webinars. At information you will find all the information you need to participate in our events and you can check if your system meets the necessary requirements to participate. If the installation of browser extensions is not possible due to your rights in the IT system, please contact your IT department. Webex is a standard nowadays and the necessary installation is fast and easy.
