Coal Sampling and Analyses
MAS provides a complete line of laboratory analyses to meet the needs of energy producers and consumers. All analyses are run in accordance with recognized industry standards such as ASTM, ISO or EPA standards. Our laboratory utilizes state of the art equipment and experienced technicians to provide fast and accurate laboratory data on coal, metallurgical coke, petroleum coke, refuse derived fuels, oils and solvents.Coal testing and analysis usually begins when the coal is still in the ground. Exploration coal core samples are drilled and analyzed for recovery and coal quality well before the mining process. During mining coal channel samples are routinely collected and analyzed for recovery and coal quality to determine the most efficient coal preparation system necessary. During preparation coal samples are collected and analyzed to assure the desired product quality is being achieved. Third party coal sampling and analysis are done routinely at loading and discharge of rail cars, trucks, barges and stockpiles. Finally, coal is routinely sampled and analyzed at the power plant to determine plant efficiency and EPA compliance.
