Best analytical performance
click here Combining an innovative mercury measuring system with a unique optical path spectrophotometer, the DMA-1 achieves a detection limit as low as 0,001 nanograms of mercury and is capable of measuring up to 30.000 nanograms of mercury, equivalent to a concentration of 300 mg/kg (300 ppm) on a 100 mg sample analysis.
see The DMA-1 produces accurate results over a wide dynamic range and on a variety of different matrices.
The results here reported refer to analyses on solid certified reference materials with a mercury concentration ranging from 5 μg/kg to nearly 5 mg/kg.
http://weselny-duet.pl/visre/pieor/385 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.
go to site The DMA-1 provides reproducible results over a broad range of samples, such as polymers, food and feed, and oils, for instance.

click The graphic shows results obtained on NIST 2709 (San Joaquin Soil), a certified reference material with known mercury content of 1.32- 1.48 mg/kg.
The DMA-1 does not virtually suffer from any memory effect.
The instrument software features the ‘Autoblank’ function, by which the user presets 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.
