Milestone DMA-80 mercury analyzers

The express analyzer for the direct analysis of mercury in firm and liquid samples without additional sample preparation. Result in 5 minutes.
The express analyzer of the last generation DMA - 80 of the Milestone company is based on the principle of the direct analysis of mercury (a method of thermal decomposition with the subsequent nuclear and absorbing analysis). The device allows to define mercury in firm and liquid samples and, in difference does not demand special preparation of tests and additional chemical reagents from the devices based on use of a method of cold steam.
The scope of the analyzer of DMA - 80 mercury is extraordinary wide: the express the analysis of foodstuff that especially for fisheries and products of a rural hozystvo, the analysis of soils and rocks, the analysis of oil products and products of processing of carbon materials, drinking and sewage, research of biological materials in medicine and animal husbandry, etc.
Main advantages of the analyzer of Milestone DMA - 80 mercury:
The exception of a stage of chemical decomposition - test decays thermally
Exception of a stage of chemical recovery of mercury - catalytic recovery directly in the camera of thermal decomposition.
Speed - about 3 - 5 minutes on one test
Reliable data irrespective of a matrix
Lack of chemical waste - is not present preparatory stages with use of chemical reagents
Profitability - lack of costs of additional chemical reagents
The autosampler (is included in the basic package) allows to work 4 hours in the autonomous mode for 40 positions - from loading of samples before receiving results. The special controller watches all stages of process of the analysis and issues the full report on results
Determination of any concentration - absolute amount of mercury in test 0.02 ng till 1000 ng (by dilution possibly to define higher concentration, and with use of a method of a prekontsentration - lower) is possible
Carrying out the analysis according to US EPA Method 7473 and ASTM D - 6722 Method is possible
Principle of Milestone DMA - 80 mercury of operation of the analyzer
1. Liquid and firm a sample are weighed on analytical scales and are located in special ditches for samples - sample boat.
2. Each sample is dried up and then szhigtsya in oxygen current.
3. Products of combustion arrive on a hot surface of the catalyst for further decomposition.
4. Vapors of atomic mercury are caught on a gold amalgamator and then quantitatively desorbed.
5. The general content of mercury decides on the help of nuclear and absorbing spectrometry at 254 nanometers.
