Eurachem Working Groups

Method Validation Working Group

  • The Eurachem Method Validation Working Group (MVWG) aims to function as a centre of expertise in the field by assembling and promoting best practice in Method Validation.

Terms of Reference

The Eurachem Method Validation Working Group has been established and will operate in accordance with the Constitution agreed in the Eurachem Memorandum of Understanding. It will function as a centre of expertise by identifying and developing best practices on how to ensure that analytical methods are fit for purpose. The MVWG is working:

  1. To provide guidance on method validation. This guidance will be applicable to all analytical laboratories and meet the requirements for accreditation;
  2. To organize - and contribute to - international seminars and workshops on issues related to method validation within analytical measurement;
  3. To collaborate and provide input on method validation into other Eurachem working groups, joint task groups and other professional liaison organisations;
  4. To follow and discuss new developments within analytical measurement, which may require new approaches regarding method validation;
  5. To contribute to the "Reading List" with relevant references on method validation in analytical measurement.

    • Extent of method validation and verification;
    • The calibration function;
    • Examples of method validation and verification.

  • The MVWG are currently preparing a webinar entitled Ensuring Analytical Excellence - The Eurachem Fitness for Purpose Guide, 3rd edition, for method validation and verification. April 2026.

  • The MVWG are currently working on a podcast to introduce the third edition of the fitness for purpose guide.

  •  The MVWG is working with other Eurachem WGs as follows:

    • With the Qualitative Analysis WG on the validation of qualitative methods;
