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.

SUPERIOR PERFORMANCE
even at the ppt level

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.

Example of reproducibility

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.

Milestone Connect

Milestone Connect offers 30-years of experience at your fingertips. 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.

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.

Compact Direct Mercury Analyzer

DMA-1


Compact Direct Mercury Analyzer

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.

Brochure

Go Direct for Mercury Analysis

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.

Best Analytical Performnce

Accurate Results

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.

Sample matrix

The DMA-1 produces matrixindependent results. The instrument is calibrated using aqueous standards and then analyzes organic and inorganic solid samples. Just one method is used to analyze a variety of different matrices making the DMA-1 extremely easy to use.

Pecision and Stability

The DMA-1 provides reproducible results over a broad range of samples, such as polymers, food and feed, and oils, for instance.
The instrument calibration lasts for months of operation, and the results are stable over time.

Memory Effect

The DMA-1 does not virtually suffer from any memory effect. The instrument software features the ‘Autoblank’ function, by which the user preset a satisfactory blank level. If that level is exceed the instrument automatically runs blank cycles until the expected level is reached. This is important when analyzing a series of unknown samples.

Sample Amount

Up to 1,5 grams of solid or 1,5 mL of liquids can be analyzed. This is particularly important for the analysis of heterogeneous materials or for samples with a very low mercury concentration.

Delivering performance with

Easy-to-Use Technology

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.
