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. 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.
  • No sample preparation or other wet chemistry prior the analysis.
  • Ease of use. Just weigh your sample, load it onto the instrument and press ‘start’.
  • Lowest cost of analysis. Speed of analysis, components’ long lifetime, sample boats durability maximum cost-effectiveness of DMA-1 mercury determination system.
  • Standard method compliance. US EPA method 7473, ASTM method D-6722-01 and D-7623-10.
  • High productivity. Complete analysis, start to finish, takes just 5 minutes.

Best analytical performance

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 produces matrix-independent 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.


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 exceeded the instrument automatically runs blank cycles until the expected level is reached. This is important when analyzing a series of unknown samples.


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.


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 an 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.
