Mercury specification CV-AFS Tekran 2500

The Tekran 2500 CV-AFS is part of the ’Mercure’ analytical park.
This park offers a wide range of analyses of the different phases of mercury (dissolved, solid and gaseous), inorganic and organic. The park consists of 3 total dissolved mercury analysers, 2 total dissolved methylmercury analysers, 2 total solid mercury analysers and 3 gaseous mercury analysers. These tools allow the speciation of mercury at ultra-trace levels (< absolute g) and in various matrices.
The CV-AFS Tekran 2500 are cold vapor atomic fluorescence spectrophotometers. They continuously measure elemental mercury under inert gas flow.
