Volatile Halogenated Hydrocarbons

• Two samples on different concentration levels
• 600 mL per sample
• Concentration range: 0 µg/L - 25 µg/L
• In round CB10 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.

The proficiency tests VHH and BTEX&MTBE in real water samples (UBA) will be offered in an alternation mode.
In 2023 BTEX & MTBE are offered and a proficiency test for VHH for real water samples will take place in 2024.
