Proftest SYKE carried out the proficiency test for the determination of chlorophyll a, oxygen, salinity, SiO2, TIC, and TOC in natural waters in May 2020 (NW 06/2020). In total, 27 participants joined in the proficiency test. Either the calculated concentration or the robust mean, the mean or the median of the results reported by the participants was chosen to be the assigned value for the measurands. For the synthetic sample of salinity the mean of the results measured by the salinometry was used as the assigned value. The performance of the participants was evaluated by using z scores. In this proficiency test 85 % of the results were satisfactory, when deviation 3.5–30 % from the assigned value was accepted. Warm thanks to all the participants in this proficiency test!
