In the event of an environmental emergency imminently threatening the safety of human life or where necessary to protect certain property, the EPA website will be updated with appropriate information. Please contact the webmaster here. After cooling, the vessel contents are filtered, centrifuged, or allowed to settle and then diluted to volume and analyzed by the appropriate determinative method.
Generally the aim of such methods is to improve analytical performance and reliability.
The accuracy of these methods depends on precise replication of the reaction conditions. While A and A are acid leaching methods, is flexibly adaptable for total digestion. You epq need a PDF reader to view some of the files on this page. Please note that all information on the EPA website may not be up to date, and transactions and inquiries submitted to the EPA website may not be processed or responded to until appropriations are enacted.
This document explains the procedure designed to mimic extraction using conventional heating with nitric acid HNO3or alternatively, nitric acid and hydrochloric acid HCl.
Amongst others, it contains procedures for field and laboratory quality control, sampling and analysis of wastes as well as guidance on how to select appropriate methods.

U.S. EPA Method 3051A: Microwave Assisted Acid Digestion of Sediments, Sludges, and Oils
Microwave Assisted Acid Digestion of Sediments, Sludges, Soils, and Oils This document explains the procedure designed to mimic extraction using conventional heating with nitric acid HNO3or alternatively, nitric acid and hydrochloric acid HCl. Apart from hot-plate based open vessel digestion methods, EPA also specifies closed-vessel microwave-assisted sample preparation procedures for the analysis of up to 26 elements. These EPA methods do not depend on the used instrument, as they prescribe temperature profiles instead of eepa power programs.
