PERFORMANCE

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 have to face a number of issues due to either the tedious sample preparation process or the analysis step. The latter, even with the UNPARALLELED

latest generation of ICP-MS or cold vapor systems, EASE OF USE

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. We are and have been the benchmark for direct mercury determination in most industries: environmental, food, energy, cement, cosmetics, agriculture, mining, and petrochemical. With thousands of DMA-80s installed in over 80 countries, HIGH PRODUCTIVITY AND

Milestone has a wealth of experience and knowledge EFFICIENCY

regarding direct mercury determination, ensuring your lab state-of-the-art technology and premium customer support.

SUPERIOR PERFORMANCE EVEN AT THE PPT LEVEL

The analysis process starts by weighing sample into a boat and IMPROVED

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 mercury D E S I G N

species are reduced and trapped on a gold amalgamator with FROM THE INSIDE OUT

subsequent release into multiple measuring cells positioned along the spectrophotometer's optical path. 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. With the DMA-80 evo, you get the right results the first time, every time.

FULL MERCURY RECOVERY

The DMA-80 evo is equipped with an advanced catalyst tube and gold amalgamator to provide high-end performance, full mercury conversion, interference removal, and fast mercury release. These components allow the DMA-80 evo to deliver fast and accurate results in a single measurement, providing symmetrical peaks and avoiding mercury overestimation or underestimation.

A SINGLE LONG-LASTING CALIBRATION FOR ALL MATRICES

A single calibration, completed using liquid or solid reference materials, suits a large variety of samples for a wide concentration range - from ppm to ppt. Moreover, because of both system stability and long working-life of the catalyst tube and gold amalgamator, calibration of the DMA-80 evo offers long-term reliability. Daily calibrations often required by conventional instrumentation are not necessary.

THE FASTEST PATH TO MERCURY DETERMINATION

The DMA-80 evo is equipped with a 40-position autosampler suitable for solid, liquid and gas samples. Samples are directly weighed in a boat, the weight is recorded by the EasyCONTROL software, then the quartz or metal boat is placed into the 40-position autosampler to begin analysis. This process is completed in as few as 5 minutes from weighing to results. Method development and sample preparation are unnecessary. The DMA-80 evo runs unattended, offers a quick turnaround time and has become a necessity for mercury determination in many labs over a wide range of applications.
