Microwave digestion is one of the most commonly used industrial technique for sample preparation during Atomic Absorption (AA) and Inductively Coupled Plasma (ICP) analyses. In microwave digestion, the combination of the sample matrix (components other than the analyte of interest) and acid is heated up to 260°C in a pressurized container. Microwave heating under high pressure breaks the sample molecules faster and dilutes them into a solution.
