dc.description.abstract Proftest SYKE carried out the proficiency test for analysis of chlorophyll, colour, conductivity, nutrients, pH and turbidity in natural waters in February 2013. In total 44 laboratories participated in this proficiency test. The sample types were: artificial water sample, coastal water and natural water. Calculated concentrations or the robust mean of the results reported by the participant were used as the assigned values for measurements. The evaluation of the performance of the participants was carried out using z score. In some cases the evaluation of the performance was not possible e.g. due to the low number of the participants. In total, 85 % of the total data in this proficiency test were satisfactory when the deviations of 2.6–35 % from the assigned values were accepted. fi
