DMA-80 direct mercury analyser has a built-in 40 position autosampler for unattended operation; simply load a sample, walk away and start obtaining accurate, reproducible results in just six minutes
The determination of mercury in fish has become a primary focal point of both private and public institutions.
These organisations make important regulatory and scientific decisions dependent upon the mercury levels found in fish tissue and therefore require a rapid, accurate method for mercury determination.
The promulgation of EPA Method 7473, which references Milestone's DMA-80 Direct Mercury analyser, means that laboratories now have at their disposal a validated EPA Method that will produce results comparable to cold vapour atomic absorption and ICP-MS in a fraction of the time, at a fraction of the cost.
Introduce a weighed sample into either a nickel or quartz sample boat and place it inside the instrument autosampler.
The sample is initially dried and decomposed and carried through a heated catalyst bed via a continuous flow of oxygen.
Mercury is trapped on a gold amalgamator and subsequently released for quantitative determination via atomic absorption spectrophotometry.
