In analytical chemistry, ashing or ash content determination is the process of mineralization by complete combustion for preconcentration of trace substances prior to a chemical analysis, such as chromatography, or optical analysis, such as spectroscopy. == Overview == The ash content of a sample is a measure of the amount of inorganic noncombustible material it contains.
