Abstract
A method of conducting microwave-assisted high pressure high temperature chemistry is disclosed. The method includes the steps of digesting a sample in a strong acid at a temperature of at least 200° C. in a pressure resistant vessel that includes a lid while exerting a defined force against the lid in order to maintain gases under pressure in the vessel; directing gas under excess pressure from the vessel into a circumferential passage defined by the vessel and its pressure resistant lid; and directing the gas from the circumferential passage outwardly from the lid while preventing gas from flowing outwardly over the edge of the vessel.
