Gaseous Hg
Page author: Angélique Carrara.
The Gardis-5 devices are part of the ’Mercury’ analytical park.
This park offers a wide range of analyses of the different phases of mercury (dissolved, solid and gaseous), both inorganic and organic. The park consists of 3 total dissolved mercury analyzers, 2 total dissolved methyl mercury analyzers, 2 total solid mercury analyzers and 3 gaseous mercury analyzers. These tools allow the speciation of mercury at ultra-trace levels (< absolute g) and in various matrices.

Gardis-5 devices are portable absorption spectrophotometers and continuously measure gaseous elemental mercury Hg0.
