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

  1. The EURACHEM Method Validation Working Group has been established and will operate in accordance with the Constitution agreed in the EURACHEM Memorandum of Understanding, and is as such working:
  2. To provide guidance on method validation. This guidance will be applicable to all chemical analytical laboratories and meet the requirements for accreditation
  3. To organize - and contribute to - international seminars and workshops on issues related to Method Validation within analytical chemistry
  4. To collaborate and provide input on Method Validation into other Eurachem working groups
  5. To follow and discuss new developments within analytical chemistry, which may require new approaches regarding Method Validation
  6. To contribute to the "Reading List" with relevant references on Method Validation in analytical chemistry.

Activities

 Past

  • MVWG was co-arranger of an international workshop, “Validation / Traceability / Measurement Uncertainty. Challenges for the 21st Century’s analysts”, in Berlin in May 2012 (see under "Completed Events")
  • The MVWG issued a revised edition of the Eurachem Fitness for Purpose guide in 2014 and is currently considering supplementary guidance on individual aspects of method validation.
  • A scientific committee based in the MVWG planned a 2-day Workshop, "Method Validation - Current Practices and Future Challenges" in Ghent, Belgium, May 2016

  • Contributing with a 3 hours workshop "Are MS-based methods fit for purpose?" at the XXII International Mass Spectrometry Conference in Florence, Italy, August 26 - 31 2018

Current

  • The MVWG is currently considering and working on supplementary guidance on individual aspects of method validation (probably to be included in a coming version of the "Fitness for Purpose" guide as annexes)
  • The MVWG is currently assembling issues for revision of the guide (due around 2019). Readers are welcome to provide inputs for this (see below)
  • The MVWG is working on illustrative examples (validation protocols) on application of the principles recommended in the "Fitness for Purpose" guide.
  • The MVWG will over time elaborate shorter leaflets pointing to application of the guide and specific issues described in the guide.

NOTE!
The MVWG will appreciate comments on the present version of the "Fitness for Purpose" guide (Ed. 2, 2014).
This can be done by using the Feedback form on Fitness for Purpose guide

    • Help provide information on the availability of PTs
    • Understand and address differences between specific sectors
    • Contribute to the development and revision of International Standards and Guides relating to PTs and other ILCs

Sampling Uncertainty Working Group

Terms of Reference

  1. The Eurachem Sampling Uncertainty Working Group, once established, will operate in accordance with the Constitution agreed in the Eurachem Memorandum of Understanding.
  2. The Eurachem Sampling Uncertainty Working Group will prepare guidance for the evaluation of uncertainties in measurement arising from the process of sampling. This guidance will be applicable to all chemical measurements that require the taking of a sample. It will provide guidance on the assessment of the uncertainty of the measurement that is caused by the process of sampling, and any physical preparation of the sample prior to analysis, and how this can be combined with estimates of uncertainty arising from the analytical process.
  3. These guides will be developed in collaboration with relevant international bodies  and will be updated as experience is gained in their use.

 

Activities

This working group is currently working to revise the Eurachem Guide "Measurement uncertainty arising from sampling". In addition, members of the group  contribute to communication and debate on this subject through conferences and publications.
