Standard Test Method for Sulfated Ash of Organic Materials by Thermogravimetry

Importancia y uso:

5.1 The sulfated ash value indicates the level of known metal-containing additives or impurities in an organic material. When phosphorus is absent, barium, calcium, magnesium, sodium and potassium are converted to their sulfates. Tin and zinc are converted to their oxides.
