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 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.

SUPERIOR PERFORMANCE

The easyTEMP contactless sensor immediately regulates the temperature of all samples and solutions, delivering precise temperature feedback and ensuring complete digestion in all vessels while maintaining outstanding safety. This technique combines the versatility of an infrared sensor with the speed and accuracy of an in-situ temperature sensor.

For each sample, the ETHOS UP programme gives digestion history traceability and temperature measurement. Temperature graphs and profiles can be kept on the ETHOS UP terminal and are displayed in real time.
These sensors, when used in conjunction with our’vent-and-reseal’ vessel technology, provide full and safe digestions with no loss of volatile substances.

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.
