The DMA-80 from Milestone is a direct mercury analyser, which uses the principal of thermal decomposition, amalgamation and atomic absorption.
The DMA-80 can analyse both solid and liquid matrices with equal precision.
Analysis takes five minutes per sample.
All mercury is released from the sample through thermal decomposition.
This eliminates the need for any sample preparation and, subsequently, purchasing, handling and disposing of hazardous chemicals so that the typical bottleneck in the analytical laboratory is eliminated.
Typical applications for the DMA-80 include: environmental, geochemical, petrochemical, food and feed, clinical and polymer samples.
The DMA-80 is fully compliant with US Environmental Protection Agency method 7473 and with ASTM method D-6722-01.
Milestone's Tri-Cell DMA-80 combines a mercury measuring system with an optical path spectrophotometer, achieving a detection limit of 0.0015ng of mercury.
The DMA-80 is matrix-independent and can analyse both solid and aqueous samples with equal efficiency.
A single method can be used to process organic and inorganic samples.
The DMA-80 is said to produce accurate results over a wide dynamic range, on a variety of different matrices.
The DMA-80 is simple to use and can also be operated in the field as well as in the analytical laboratory.
The DMA-80 has been shown to save laboratories more than 70 per cent in costs when compared to traditional mercury analysis techniques such as CV-AAS.
