The Milestone DMA-80 evo is a direct mercury analyzer of solid, liquid, and gas samples. Analysis time is 5 minutes only and no sample preparation is required.

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 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 double beam dramatically increases 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

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.

Milestone Connect also extends instrument control to your smartphone, tablet or PC, allowing remote monitoring of the system. With Milestone Connect you get instant access to support 24/7.

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.

DMA-80 evo schematics

The DMA-1 mercury determination system does not require any sample preparation or other wet chemistry before the analysis. This means ease of use, low running cost and no more necessity to purchase, handle and dispose hazardous chemicals.

Milestone DMA-1 is a direct mercury analyzer of solid, liquid, and gas samples. Analysis time is 5 minutes only and no sample preparation is required. The DMA-1 analyzer is based on the principles of sample thermal decomposition, mercury amalgamation and atomic absorption detection. The DMA-1 shares the same technology of the Milestone DMA-80 series, the most successful direct mercury analyzer in the market with thousands of units installed in 80 different countries worldwide.

The DMA-1 achieves a detection limit as low as 0,003 nanograms of mercury and is capable of measuring up to 1.500 nanograms of mercury, equivalent to a concentration of 15 mg/kg (15 ppm) on a 100 mg sample analysis.

The DMA-1 is operated via a compact control terminal with easy-to- read, bright, full-color, touch screen display or, alternatively, by a Windows-based computer. The terminal is provided with multiple USB and RS-232 ports for direct printouts of methods and runs, and for interfacing the instrument to an external balance.

The terminal runs Milestone’s unique EasyCONTROL software, providing simple and intuitive, but extremely flexible and powerful control over the analytical process. All sample parameters, including furnace temperatures, method profiles, absorbance signals, results, and calibrations are saved.
