Best analytical performance
Combining an innovative mercury measuring system with a unique optical path spectrophotometer, the DMA-80 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.
The DMA-80 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 over 25 mg/kg.
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.
The DMA-80 provides reproducible results over a broad range of samples, such as polymers, food and feed, and biologicals for instance.
The DMA-80 produces matrix-independent results.
The instrument is calibrated with aqueous standards and analyzes organic and inorganic solid samples.
Just one method is used to analyze different matrices making the DMA-80 extremely easy to use.
10 ng of mercury from aqueous mercury standard, NIST 2709 Soil and NIST 1632c Coal, generate the same absorbance peaks.
The DMA-80 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.
