Total Mercury AMA 254

The AMA-254 is part of the ’Mercury’ analytical park.
This park offers a wide range of analysis 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 methyl mercury 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 AMA-254 is an atomic absorption spectrophotometer and continuously measures elemental mercury under oxygen flow.
