Volatile Halogenated Hydrocarbons
- Two samples on different concentration levels
- 600 mL per sample
- Synthetic samples, concentration range: 0 µg/L - 25 µg/L
- The specified standard deviations for proficiency assessment (z-score-criteria in %) and lower limits apply to synthetic samples in the year 2021
and are calculated from interlaboratory comparisons 2010-2020. At regular intervals the standard deviations are recalculated and updated.

The proficiency tests VHH and BTEX&MTBE in real water samples will be offered in an alternation mode.
In 2021 BTEX & MTBE are offered and a proficiency test for VHH for real water samples will take place in 2022.
