The KECO 204 PermaStream accurately measures total hydrocarbons / VOCs including aliphatic and aromatic hydrocarbons.
The water sample continuously flows into the analyzer and the heated PermaStream unit effectively strips the hydrocarbons in the water based on Henry’s Law.
A carrier air then sweeps the hydrocarbons from the PermaStream and transports them to the metal-oxide sensor for a quantitative analysis.
