Save Time. Go Direct for Mercury Analysis

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 known to analysts who who often face a number of issues connected with tedious sample preparation process or the mercury analysis steps causing memory effect even after long cleaning cycles performed using latest generation of ICP-MS or cold vapor systems.
The DMA-80 mercury determination system can analyze any matrix (solid, liquid or gas) without any pre-treatment or chemical additions in as few as 6 minutes in full compliance with EPA method 7473. With thousands of units installed, Milestone defines the benchmark for direct mercury determination a wide range of industries: environmental, food energy, cement, cosmetics, agriculture, mining and petrochemical.

The evolution of mercury determination technology for Food Samples

Go direct for any sample

and every sample

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.

Low running costs

with superior ROI

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.
Low running cost

Superior Performance

even at the ppt level

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.

Long-lasting calibration

for all matrices

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.

Forget about memory effect

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 productivity.

Improved design from the inside out

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.
