Metals and Trace Elements
- Two samples on different concentration levels
- 250 mL per sample
- Natural samples: one ground water sample, one surface water sample (partly fortified)
Details: UBA and Annual Programme 2024
- Synthetic samples (IFA): Concentration range: µg/L-level, more details can be found here.
- The specified standard deviations for proficiency assessment (z-score-criteria in %) and lower limits apply to synthetic samples in the year 2024
and are calculated from interlaboratory comparisons 2013-2023. The standard deviations are recalculated and updated at regular intervals.
