The vessel is sealed and heated in the microwave unit for a specified period of time. Apart from hot-plate based open vessel digestion methods, EPA also specifies closed-vessel microwave-assisted sample preparation procedures for the analysis of up to 26 elements. This document explains the procedure designed to mimic extraction using conventional heating with nitric acid HNO3or alternatively, 3051 acid and hydrochloric acid HCl.
