The Milestone DMA-80 has been at the forefront of
direct total mercury analysis for almost two decades.
The challenges in mercury determination are well know
to analysts who have often had to face a number of
issues due to either the tedious sample preparation
process or the analysis step. The latter, even with the
latest generation of ICP-MS or cold vapour systems,
may create a memory effect even after long cleaning
cycles. The DMA-80 can analyze any matrix (solid,
liquid or gas) without any pre-treatment or chemical
additions in as few as 6 minutes. With thousands of units installaed, we are the benchmark for direct mercury determination in most industries: environmental, food energy, cement, cosmetics, agriculture, mining and petrochemical.
Improved design from the outside out for superior performance event at the ppt level.
Easy-to-use technology with a single long-lasting calibration for all matrices.
No memory effect thanks to the revolutionary autoblank feature.

Fully compliant with US EPA Method 74731, ASTM method D-6722-01 and D-7623-10.
Maximize your ROI with an easy-to-maintain system and repliable components.
Short and focused technical paper on mercury determination technology and application, integrated with analytical data.
The DMA-80 evo has seamlessly integrated a wide
range of applications and industries. It
is used for for mercury determination in
environmental applications such as soil,
wastewater, sediment and waste
testing. It has also been adopted into
the food industry, where fish testing
is the primary application.
The DMA-80 evo is an
easy-to-maintain system with a low running cost. Its advanced components are synonymous
with reliability, ensuring the same quality over and over again. The DMA-80 evo runs perfectly with either compressed
air or oxygen as a carrier, providing additional savings to your lab without compromising on performance.
The DMA-80 evo double beam dramatically
reduces the signal to noise ratio, which greatly improves the
quantification limit, enabling accurate and precise mercury
determination even at the ppt level. This increased signal stability improves the reproducibility and reliability of analysis even at low concentrations.
A single calibration, done withusing liquid or solid references materials, suits all wide variety of samples, over a
wide concentration range: from ppt to ppmwith concentrations ranging from PPM to PPT. The DMA-80 evo’s
calibration provides long-term reliability thanks to the stability of the system and the long lifetime of the
catalyst tube and gold amalgamator.
These features allow you to eliminates the
daily calibrations often required by conventional instrumentation.

Milestone’s DMA-80 evo fully overcomes it with a
revolultionary feature: the Autoblank. This, along with the
other high performance components of the system, eliminates
overestimation and ensures low blanks, thus enhancing user
confidence in the data collected, while still ensuring high

The analysis process starts with weighing sample into a boat and then running it through thermal decomposition under air or oxygen flow. All mercury and residual combustion products then flow into the catalyst section. Here, interferences are removed and the mercury species are reduced and trapped on a gold amalgamator with subsequent release into multiple measuring cells positioned along the spectrophotometer's optical path. The DMA-80 evo double beam dramatically reduces the signal to noise ratio, which greatly improves the quantification limit, enabling accurate and precise mercury determination even at the ppt level. This increased signal stability improves the reproducibility and reliability of analysis even at low concentrations.
