Volatile Halogenated Hydrocarbons
- Two samples on different concentration levels
- 600 mL per sample
- Natural samples: one surface water, one ground water (partly fortified)
further details: UBA and Annual Programme 2022.
- Synthetic samples, concentration range: 0 µg/L - 25 µg/L
- In round CB09 there is the possibility to order BTEX/MTBE and VHH together at a reduced price.
- The specified standard deviations for proficiency assessment (z-score-criteria in %) and lower limits apply to synthetic samples in the year 2022
and are calculated from interlaboratory comparisons 2011-2021.
At regular intervals the standard deviations are recalculated and updated.
