Acrylamide (AA)is a substance that has found widespread application in industry, e.g. for the purification of drinking water and in food packaging. Due to its toxicological properties, legal limits have been set both for drinking water and for migration into food.
Following a request of the participants of the European Workshop on "Analytical methods for the acrylamide determination in food", the Institute for Reference Materials and Measurements (IRMM) of the European Commission’s Directorate General Joint Research Centre (DG JRC) organised an inter-laboratory comparison test on the determination of AA in butter cookies and crispbread samples. One goal of the collaborative trial was the evaluation of the performance of laboratories at an AA level close to the limit of quantification (LOQ) . Another goal was the elucidation of the most critical steps in the applied analysis protocols. For that purpose, a raw bread extract and a spiked bread extract were shipped with the food samples. The set of samples was completed by AA standard solutions, which were prepared by dissolution of solid AA in appropriate solvents.
The study was a dedicated collaborative trial and was free of charge for the participants. It was announced via the Directorate Health General and Consumer Protection (DG SANCO) to the national food authorities of EU Member States and EU Candidate Countries. Additionally all participants of the above-mentioned workshop were informed by email. Information concerning the application procedure for the study was also available on the homepage of the Food Safety and Quality Unit (FSQ) of IRMM.

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.
The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
