Eurachem Workshop: Quality in Analytical Measurements (2014)


Eurachem ran an international workshop on  "Quality in Analytical Measurements" in Lisbon on Monday 19 to Wednesday 21 May 2014. This workshop covered the most challenging technical details of the analytical process, including the chemical description of the analytical problem, producing measurements with adequate traceability and uncertainty, interpreting results based on objective evidence and reporting results to the client. The workshop included invited lectures, short communications, poster sessions and breakout sessions.

The event also celebrated the 25th Anniversary of Eurachem.

Further information on the technical content can be found on the workshop website maintained by the University of Lisbon faculty of chemistry.

In addition, a summary of the workshop has been published in the journal Accredditation and Quality Assurance: see R Bettencourt da Silva, A Williams, Eurachem workshop on quality in analytical measurements: from specification to decision, Accred.

Scientific programme

This workshop considered the most challenging technical details of the analytical process, including the chemical description of the analytical problem, producing measurements with adequate traceability and uncertainty, interpreting results based on objective evidence and reporting results to the client. Breakout sessions provided the opportunity to identify areas where problems remain. Topics covered included:

  1. Specification for measurements
  2. Product compliance assessment
  3. Procedure Validation/ Verification
  4. Measurement Uncertainty
  5. Measurement Traceability
  6. Proficiency testing
  7. Training

Presentations and posters covering these topics were invited and the list of contributions, with electronic copy where available, is given below. The workshop website also holds details of the scientific programme and available presentations.
