Ashing furnaces are chamber furnaces which are designed to allow materials to be burned at a closely controlled temperature. Air is drawn into the chamber by the tall chimney and is forced to pass between the insulation layers so that it is pre-heated before entering the chamber. This ensures that samples near the air inlet are not cooled by ...

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.

Dry Ashing is usually performed by placing the sample in an open inert vessel and destroying the combustible (organic) portion of the sample by thermal decomposition using a muffle furnace. Typical ashing temperatures are 450 to 550 C. Magnesium nitrate is commonly used as an ashing aid. Charring the sample prior to muffling is preferred.
