Uniform analyses for clean drinking water in Europe- PTB
PTB scientists receive award for concept of comparability and traceability of water analyses
Clean water is a matter of survival for humans, particularly when it is used for drinking, cooking and for food manufacture.
Nationally and internationally, chemical measurements are compared as a rule by round-robin tests. Hereby, the participating laboratories receive samples of unknown concentration for analysis.
Therefore, the EU member countries have in several guidelines undertaken to guarantee their citizens sustainable clean drinking water. The requirement for this is, however, a water analysis that provides the exact values for possible toxic substances, which are then also internationally comparable. Therefore, scientists from the Physikalisch-Technische Bundesanstalt (PTB), together with researchers from the University of Stuttgart (AQS BW) and the Rhenish-Westphalian Institute for Water Research (IWW) have worked out new metrological concepts as to how the comparability of measurement results can be achieved without additional time and effort.
