EPA 3051A

U.S. EPA Method 3051A: Microwave Assisted Acid Digestion of Sediments, Sludges, and Oils

Applicability: EPA Method 3051A is primarily used for preparing samples for the analysis of metals. It involves digesting samples using microwave heating with concentrated nitric acid (HNO3) or a combination of nitric and hydrochloric acids (HCl). This method is applicable to a wide range of materials, including sediments, sludges, soils, and oils. It’s designed to be an alternative to conventional acid digestion methods like EPA Method 3050.

Purpose: The primary purpose is to prepare solid samples for the analysis of various elements, such as metals, by techniques like atomic spectrometry.
