EPA Method 3050B

EPA Method 3050B is a standardized procedure used to prepare soil, sediment, or sludge samples for analyzing trace metals. It involves digesting the sample with a mixture of acids—primarily acidified nitric acid and hydrochloric acid—to break down complex materials and release metals into solution. This process ensures that metals are available for measurement by analytical techniques such as ICP-OES or ICP-MS, providing accurate data on contamination levels. Method 3050B is widely used for environmental testing to assess pollution and ensure regulatory compliance.
