Acid digestion

Organic sample materials are digested with oxidising acids (especially nitric acid or nitric acid with hydrogen peroxide) and are completely mineralised. Fat-containing samples react exothermically. This must be taken into account in temperature control and temperature regulation. Hydrocarbons are oxidatively converted into carbon dioxide gas. Inorganic samples such as metals, oxides, etc. are digested with specific acid mixtures. A general recipe is not available.
