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
The DMA-1 analyzer is based on the principles of sample thermal
decomposition, mercury amalgamation and atomic absorption
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,
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.
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
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.
Precision 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.
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
