Welcome to Eurachem, a network of organisations in Europe having the objective of establishing a system for the international traceability of chemical measurements and the promotion of good quality practices. It provides a forum for the discussion of common problems and for developing an informed and considered approach to both technical and policy issues. It provides a focus for analytical chemistry and quality related issues in Europe.

At the Eurachem General Assembly in May 2021, two Executive Committee (EC) members – Kyriacos Tsimillis (Cyprus) and Wolfhard Wegscheider (Austria) – were re-appointed, and we welcomed a new Elected member, Helen Cantwell, of Eurachem Ireland.
Thanks to the work of our colleagues in Ukraine, the Eurachem Method Validation Working Group is pleased to publish a Ukrainian translation of our Validation Guide Supplement on the planning and reporting of validation studies.
The planning supplement is in the form of a template for planning the evaluation of chosen performance characteristics, which can form the basis of a validation report. The supplement also contains a checklist to assist with validation planning.
Thanks to the our Eurachem colleagues in Finland, the PT Working Group is pleased to publish a Finnish translation our Information Leaflet on Investigating Poor Performance in PT. The leaflet gives advice for laboratories on how to best to follow up and address any poor results in proficiency testing.
Thanks to our colleagues at Eurachem-ES and Eurolab-ES in Spain, Eurachem has published a new Spanish translation of the 2nd edition of the Eurachem/CITAC Guide "Measurement Uncertainty Arising from Sampling".
The Guide describes various methods that can be used to estimate the uncertainties arising from the processes of sampling and the physical preparation of samples. It is intended primarily for specialists such as sampling planners and for analytical chemists who need to estimate the uncertainty associated with their measurement results.
The Eurachem working group on Uncertainty from Sampling has published a new Information Leaflet introducing the idea of the "uncertainty factor". The leaflet, which was developed jointly with the RSC Analytical methods Committee, explains how an uncertainty factor can be used to provide a convenient and realistic uncertainty interval in circumstances where a simple symmetric interval is not suitable.
