Eurachem currently has the following active working groups:

Qualitative Analysis Working Group

Introduction

At the Eurachem/CITAC workshop Measurement uncertainty and traceability: meeting the requirements of ISO/IEC 17025  in Lucerne, June 2002, a workshop session was held on the topic of uncertainty in qualitative analysis and testing. That workshop recommended the formation of a new Eurachem working group to provide guidance on the topic, based on the discussion paper presented at that meeting. The following constitutes the Terms of Reference for the working group.

Activities

The Eurachem working group is working on uncertainty issues in qualitative analysis, in response to early concerns about the implementation of measurement uncertainty under ISO 17025 accreditation. Eurachem published a policy paper on the subject in 2000 [i].At the Eurachem/CITAC workshop Measurement uncertainty and traceability: meeting the requirements of ISO/IEC 17025  in Lucerne, June 2002, a workshop session was held on the topic. That workshop recommended the formation of a new Eurachem Qualitative Analysis Working Group  to provide guidance on the topic, based on a discussion paper presented at that meeting. The group met first in May 2003. It is currently working on the topic of the assessment and expression of uncertainty in qualitative analysis and testing. The aim is to provide guidance on issues such as:

  • the effort required to obtain sufficiently reliable false response rates (the most common basis for assessing the reliability of qualitative tests)
  • methods of determining false response rates, including experimental methods, methods based on databases, and prediction of false response rates from the performance of quantitative methods used in the testing process
  • practical methods of expressing the performance of methods, including guidance on the wide range of different terminology in use.

The group is working in cooperation with CITAC, and includes some US representatives as well as European members. The curent draft guidance is divided int two principal sections, one covering policy issues such as the use and reporting of uncertainty in qualitative tests (based on the policy paper above [6]), and the other on technical methods for assessing and expressing uncertainty in qualitative tests. Eurachem currently take the position that measurement uncertainties in the test method control parameters (such as times, temperatures etc.) should be demonstrably under control, that at least the most important false response rate should be assessed and that it is desirable to assess both false positive and false negative rates. Eurachem does not consider that the general requirements covering measurement uncertainty reporting should extend to the provision of probabilistic information in qualitative test reports. This is largely because such estimates are based on probabilties which are themselves very hard to estimate reliably. The latter part of the guidance covers the estimation or experimental determination of false response rates, using experiment, probabilistic modelling, database match rates etc. An earlier published paper describes many of the relevant issues [ii]. The methods are very closely related to procedures appropriate for validation of qualitative methods, a topic which the group sees as important but not yet fully addressed.

Eurachem Education and Training Work Programme

1. Collate and evaluate information on the state of education and training in analytical science in different member states in particular with respect to the development of teaching aids and training materials on quality management which emphasise metrology.

2. Contribute to the development and delivery of education and training in chemical metrology and quality assurance for both analytical scientists and the broader community by producing freely available materials. Current activities are:

  • Development and maintenance of a reading list to support teaching and training of metrology in chemistry and quality assurance. Click here to access the reading list.
  • Revision of the Eurachem/CITAC 'Guide to Quality in Analytical Chemistry: An aid to accreditation'
  • Revision of the Eurachem Guide 'Terminology in Analytical Measurement:Introduction to VIM 3'

 3. Organise workshops in metrology in chemistry which bring together academic staff, industrial scientists, instrument manufacturers and students.

4. Collaborate with other interested organisations such as EuCheMS, Eurolab, IRMM for TrainMiC and AcadeMiC, UK Chemical and Biological Metrology programme.

Specific projects in each area will be agreed at the annual Working Group meeting. Each work package will have a group of members identified in the Minutes to carry the project forward.

Work Programme

Guides

Information leaflets

The working group has so far published four information leaflets:

In addition, the WG maintains the leaflet Measurement Uncertainty for Laboratory Customers, originally published by SP and elaborated with Eurolab and others to help customers understand why laboratories report measurement uncertainty.

Workshops

The Measurement Uncertainty and traceability working group has coordinated several International workshops on measurement uncertainty, including

  • Evaluation of measurement uncertainty (Graz, 1994; Berlin, 1997, Lisbon, 2011)
  • Measurement Uncertainty in Sampling and Compliance (Berlin, 2008)
  • Eurachem Workshop: Quality in Analytical Measurements (Lisbon, 2014)

Current Activities

  • Organisation of the 9th International Workshop on Proficiency Testing in Analytical Chemistry, Microbiology and Laboratory Medicine
  • Preparation and translation of a series of information leaflets regarding topics of interest to PT, to encourage good practice across Europe
  • Production of a guide on the evaluation of qualitative results in PT schemes

A key role of the PTWG is to discuss both input and outcomes of issues addressed at the EA/Eurolab/Eurachem Working Group on Proficiency Testing in Accreditation (EEE-PTWG). The EEE-PTWG discusses issues that go much wider than analytical chemistry, and it is the responsibility of the EURACHEM representatives to ensure that any decisions and outputs of the WG take into account the needs of analytical chemistry. Current representatives of the PTWG who represent Eurachem on the EEE-PTWG are Brian Brookman and Piotr Robouch. In addition Frank Baumeister (Germany) and Renata Borroni (Italy) are also Eurachem representatives.
