During May 20-21, 2019 the Eurachem 2019 Scientific workshop Validation of targeted and non-targeted methods of analysis took place in Dorpat Conference Centre in Tartu. This workshop also marks the 30th anniversary of Eurachem. This workshop is the first event in the EACH “Data Quality in Analytical Chemistry” conference series.

Approximately 160 people attended the workshop, which is the largest number of participants in the history of Eurachem workshops! The participants were from 42 countries of the member countries in Eurachem as well as Asia, North America, South America and Middle East. The farthest participants were from Fiji, the Philippines, Uruguay and Brazil.

The workshop was held with 13 oral presentations from established researchers, young scientists as well as industries. Together with 22 posters all presentations reflected the current and potential future developments related to methods validation. The workshop addressed the current status of analytical method validation in general and specifically validation of the non-targeted methods (i.e. ones where the analyte is not defined beforehand). With the speaker permissions, all presentations will shortly be available at the Eurachem website. In addition to presentations, each day a Working Group session was organised with 3 topics in parallel (Image on the left: Welcome by Dr Marina Patriarca, the Eurachem chair).

Non-targeted methods are an especially noteworthy part of the programme, because their validation involves specific issues and their validation is significantly less developed than validation of targeted methods (i.e. the “normal” analytical methods, where the analyte is known beforehand). At the same time non-targeted methods are becoming increasingly important in environmental protection, food safety, different omics areas, etc. (Image on the right: Prof. Jon Benskin from Stockholm University presenting an introduction to non-targeted analysis)

All sessions raised new issues and challenges, especially related to non-target method validation. The workshop clearly was also very inspirational for Eurachem from the point of view of preparing new guideline materials – especially the topics related to non-targeted analysis are still essentially not covered by official guidance documents.

Some example topics of the workshop: Validation of targeted methods: where are we? Validation of non-targeted methods – differences from targeted methods. Detection of a multitude of (unknown) components in complex samples: criteria for identification. Managing the huge amounts of complex data from non-targeted methods. Recent instrumental developments. Software tools for validation. (Image on the left: Dr. Koit Herodes presenting the ValChrom validation software)

The workshop certaily had a significant educational value and we are pleased by the large number of student participants: altogether close to 50! The international master’s programmes Excellence in Analytical Chemistry and Applied Measurement Science were both heavily represented: the majority of students of those programmes participated in the workshop (Image on the left: EACH and AMS students at the workshop).

The workshop was jointly organized by Eurachem and ECAC (University of Tartu, Tallinn University of Technology and the Estonian Environmental Research Centre).
