Milestone DMA-80 Direct Mercury
analyzer
Composed of:
- Control Terminal
- 40 position autosampler
- Combustion chamber, catalyst oven,
and gold amalgamator
- Single beam spectrophotometer with
sequential flow through two measurement cells
- DMA-80 software
The DMA-80 is capable of detecting
total mercury in ppm and ppb ranges without previous sample preparation.
Elemental mercury is delivered to the silicon UV detector by oxygen as a
carrier gas and is measured by atomic absorption spectrometry.
Current Applications:
Sample Matrices:
Solids and liquids, for example
- Soil
- Water (ppm levels)
- Animal tissue
- Plant material
- Insects
