Eurachem is a leading analytical chemistry organization in Europe, which has main objectives of

icon5Establishing a system for traceability of chemical measurements

icon5Promoting good laboratory practice.


Eurachem enables discussions between laboratories to solve common problems and to develop co-operation.

To date there are 32 member states and every member has assigned an official organization to be held accountable for the representation. In Estonia the official organization is Estonian Environmental Research Centre in collaboration with the University of Tartu. Once a year a general assembly is held with a scientific workshop to discuss and solve a point at issue.

The official representatives from Estonia are:

Dr. Riin Rebane (Estonian Environmental Research Centre )

Prof. Ivo Leito (University of Tartu)



As Eurachem is concerned in very broad topics, smaller expert working groups have been established. These working groups produce freely-accessible guides, initiate workshops and promote co-operation. To date there are 7 expert working groups and every working group is engaged in a more specific topic in analytical chemistry (e.g. validation, measurement uncertainty, proficiency testing, qualitative analysis).


In 2018. the yearly general assembly and workshop take place 14th – 18th May in Dublin, Ireland. The main theme of the workshop is “Data – Quality, Analysis and Integrity”.





Quality assurance, accreditation and terminology

Guide to Quality in Analytical Chemistry – A general guide to laboratories on how to carry out the analytical procedures with high quality.

Accreditation for Microbiological Laboratories – A guide to microbiological laboratories on how to fulfil the requirements of ISO 17025.

Quality Assurance for Research and Development and Non-routine Analysis – A guide to assure quality in non-routine laboratories.

Terminology in Analytical Measurement


Proficiency testing:

Selection, Use and Interpretation of Proficiency Testing (PT) Schemes


Measurement uncertainty and validation:

Quantifying Uncertainty in Analytical Measurement

Measurement uncertainty arising from sampling

Use of uncertainty information in compliance assessment

Setting and Using Target Uncertainty in Chemical Measurement

The Fitness for Purpose of Analytical Methods – The most popular guide by Eurachem

Harmonised Guidelines for the Use of Recovery Information in Analytical Measurements

Traceability in Chemical Measurement

The Selection and use of Reference Materials


All the guides are first published on the Eurachem webpage.
