Sulfated Ash Determination for Pharmaceutical Quality Control

The wet digestion is used to remove all carbonous material from the sample. The remaining inorganic content can be weighed out, resulting in the sulfated ash, or then be used for further elemental analysis. The digestion is performed using concentrated sulfuric acid while heating the mixture. The heat is ramped automatically using the BUCHI Wet Digester B-440. Once the sulfuric acid has digested the sample and is evaporated, the sample is eventually ashed in a muffle oven to remove any remaining organic material.
