1049 Coal and Fly Ash - Final - Application Note

The level of mercury found in coal can vary dramatically. Using clean fuels may be critical in satisfying emission requirements for the Mercury Rule of the Clean Air Act (CAA). Also, the monetary value of the fly ash residue resulting from the combustion of coal may be inversely proportional to its mercury content. The Hydra-C Direct Mercury Analyzer provides fast, simple and convenient analyses of these materials without sample pretreatment or production of hazardous chemical waste. A typical sample analysis takes about 5 minutes. The Hydra-C employs U.S. EPA Method 7473 which has been approved for both laboratory and field analysis.
