EPA Method 3005 Instrumentation Guide

EPA Method 3005 is a widely utilized sample preparation method for the determination of total recoverable metals in aqueous samples. It involves an acid digestion process to break down complex matrices and release trace metals into solution, making them suitable for analysis using Inductively Coupled Plasma Mass Spectrometry (ICP-MS) or Atomic Absorption Spectroscopy (AAS). This method ensures compliance with environmental regulations by accurately quantifying elements such as lead, cadmium, arsenic, and mercury in drinking water, wastewater, and industrial effluents.
