Dry ashing is an alternative means of sample preparation and is accomplished by heating the sample in an open dish or crucible in air. Very often this is done in a muffle furnace located in a clean room. The stages of dry ashing include: sample drying, evaporation of volatile materials, and progressive oxidation of the non-volatile residue until all of the organic matter is destroyed.
