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.
● Improved design from the outside out for superior performance event at the ppt level.

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 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.
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.

This web-based app allows you to become a part of the Milestone community and gain exclusive access to a robust library of information: lists of parts, technical notes, user manuals, video tutorials, continuously updated application notes and all relevant scientific articles. 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.

At Kovalent we strive to establish and develop long-term partnerships with our customers. When we use the word “partnership” we mean that Kovalent becomes an integral part of our customers’ projects, where we are expected to fully understand their application needs. We aim to make Kovalent our customers’ first and natural choice, and this ambition permeates our entire organisation from initial contact to finished and delivered product.
Genetec is a member of the same family of companies as Kovalent. Both companies share the same set of values and are in many ways integrated with each other. The main difference between the two companies are their products. Kovalent is involved in system solutions including instrumentation and Genetec is mainly working with consumables. The focus of Genetec is chromatography accessories. You are welcome to visit their state of the art web shop: genetec.se
