DIRECT MERCURY ANALYSIS
Direct mercury analysis offers a straightforward procedure toward mercury determination completely removing the sample preparation step and offering great analytical performances. Milestone has been at the forefront of direct mercury analysis for over two
decades. The DMA-1 evo offers to laboratories, an affordable path, to adopt direct mercury determination.
Designed to match the needs of laboratories with limited throughput in mercury determination, it offers a rugged, compact, and economical solution to several industries such as environmental, food, energy, cement, cosmetics, agriculture, mining, and petrochemical
PRINCIPLE OF OPERATIONS
The analysis starts by weighing a sample inside a boat and subsequently running it through thermal decomposition
under a flow of air or oxygen. All mercury and residual combustion products then flow into the catalyst section. Here,
interferences are removed, and mercury residues are reduced and trapped in a gold amalgamator with subsequent
release into two measuring cells positioned along the spectrophotometer’s optical path. The ability of the catalyst
to remove any interferences along with the fast release of mercury from the amalgamator ensures a precise and
accurate determination. With the DMA-1 evo, you get the right results not only the first time, but every time.
