Coal burning plants are recognised as the largest source of man-made mercury pollution. This has lead to stronger regulations on allowable mercury emission creating a need for fast, reliable mercury testing in coal and coal combustion products.
Milestone DMA-80 direct mercury analyser, available from John Morris Scientific , enables users to directly analyse coal and coal ash samples. With the Milestone DMA-80 direct mercury analyser users can analyse coal and coal ash samples in approximately 7 minutes and eliminate the need for expensive chemicals and labour intensive sample preparation. Users need to place the sample directly in the instruments and press Start. A built-in 40-position auto sampler allows unattended operation while a wide dynamic range and low detection limits provides maximum throughput, accuracy and versatility.
Direct mercury analysis is an industry accepted process and has been used to generate US EPA method 7473 ‘Mercury in Solids and Solutions by Thermal Decomposition, Amalgamation, and Atomic Absorption Spectrophotometry’ and ASTM method D-6722 ‘Total Mercury in Coal and Coal Combustion Residues by Direct Combustion Analysis’.
