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.
