DMA-80 Direct Mercury Analyzer

5-minute Direct Mercury Determination in solid and liquid samples

Since its introduction in 1999, over 800 units have been installed worldwide!
The DMA-80 offers accuracy, precision, simplicity and speed!

NO SAMPLE PREPARATION
The DMA-80 enables the operator to do direct determination of total mercury without the need for acid digestion or other wet chemistry sample treatment prior the analysis; this means no hazardous chemicals to purchase, handle and dispose.

HIGH PRODUCTIVITY
Typical analysis time is 5 minutes. A dual-tray autosampler allows for unattended analysis of multiple samples.

EXTREMELY LOW DETECTION LIMIT
Milestone’s Tri-Cell DMA-80 combines an innovative mercury measuring system with a unique optical path spectrophotometer, achieving a detection limit of 0,0015 ng of mercury.

MATRIX-INDEPENDENT RESULTS
The DMA-80 is matrix-independent and can analyze both solid and aqueous samples with equal efficiency. A single method can be used to process organic and inorganic samples.

EASE OF USE
All you need to do is weigh your sample, load it onto the built-in auto-sampler and press ‘start’. The DMA-80 is so simple to use that it can also be operated in the field, not only in the analytical laboratory. See how the DMA-80 works

LOW RUNNING COST
The DMA-80 has been shown to save laboratories more than 70% in costs when compared to traditional mercury analysis techniques like CV-AAS. Learn More

EASY MAINTENANCE
All the DMA-80’s components, such as the catalytic furnace, amalgamator and spectrophotometer, are easily accessible for routine maintenance and cleaning. Learn More

LARGE INSTALLED BASE
With hundreds of DMA-80’s installed globally, Milestone is the acknowledged market leader in direct mercury analysis. Our extensive experience enables us to provide the highest level of applications and support.

US EPA AND ASTM METHODS ALREADY AVAILABLE
The DMA-80 is fully compliant with US EPA method 7473 (Mercury in solids and solutions by thermal decomposition, amalgamation, and atomic absorption spectrophotometry) and with ASTM method D-6722-01 (Standard test method for total mercury in coal and coal combustion residues by direct combustion analysis).

US EPA Method 7473

Method 7473 is designed for the determination of mercury in solids, aqueous samples, and digested solutions in both the laboratory and field environments. The stability of the instruments is such that field and lab results are statistically identical. Due to the severe toxicity of mercury and to its pervasive pre-RCA mismanage-ment, the EPA envisions widespread use of this technology.
