U.S. EPA Method 3051A: Microwave Assisted Acid Digestion of Sediments, Sludges, and Oils
Since this method is not intended to accomplish total decomposition of the sample, the extracted analyte concentrations may not reflect the total content in the sample. While A and A are acid leaching methods, is flexibly adaptable for total digestion. This microwave extraction method is designed to mimic extraction using conventional heating with nitric acid HNO3or alternatively, nitric acid and hydrochloric acid HClaccording to EPA Method Contact Us to ask a question, provide feedback, or report a problem.

EPA Method 3051A
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. Generally the aim of such methods is to improve analytical performance and reliability. In the event of an 3051q emergency imminently threatening the safety of human life or where necessary to protect certain property, the EPA website will be updated with appropriate information.
