The EURL Berlin is planning to organise two proficiency tests in 2021. Scheduled for the first and second quarter is a proficiency test on precision and accuracy in the analysis of standard solutions (STRD0421). Participating laboratories will be provided with 3-4 mix solutions of analytes belonging to several substance groups and are asked to determine the analyte contents. This PT will be the first of its kind organised by the EURL Berlin and shall give the participants the opportunity to check their own standard solutions against a gravimetrically prepared solution. The test items are projected to ship in April.

The EURL Berlin’s second PT in 2021 will focus on the determination of nitroimidazoles in plasma and milk (NIIM0921). The participants will be provided with 3-4 test items produced from incurred samples. All participants who do not currently analyse nitroimidazoles in milk will be asked to either apply the method they routinely apply for plasma samples or to apply the method developed by the EURL Berlin. The test items are projected to be shipped in September.
