DMA-80 Direct Mercury Analyzer
5-minute Direct Mercury Determination in solid and liquid samples
Since its introduction in 1999, over 700 units have been installed worldwide.
DMA-80 employs the thermal decomposition technique and directly and easily analyzes samples, eliminating digestion, chemical pretreatment and waste disposal.
Standard mercury methods like Cold Vapor involve lengthy sample pretreatment that can involve a digestion and/or chemical oxidation followed by chemical reduction of the mercury to its elemental state. Sample preparation can take several hours and the reagents involved must be disposed of according to strenuous guidelines for solid and hazardous waste.
Milestone is the only company that directly develops, engineers, manufactures and sells (through its network of exclusive distributors) a dedicated mercury analyzer.
Main Advantages
- Speed: results in 5 minutes
- Results are matrix independent
- Small footprint ideal for laboratory and field analysis
- No sample digestion step and no chemical pretreatment step
- Eliminates use of reagents and their disposal
- Validated results for both solid and liquid matrices
- Intuitive user interface or Windows®-based operating software for your PC
- Auto-sampler allows unattended and unlimited operations
- Removable flash card for data storage (for unit with terminal)
- LIMS capabilities
The DMA-80 offers accuracy, precision, simplicity and speed!
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.
