ASTM E2403 – Sulfated Ash of Organic Materials by Thermogravimetry (TGA)

 

We perform testing by ASTM E2403 to determine the sulfated ash content (sometimes called residue-on-ignition) of organic materials by thermogravimetry. The method converts common metals found in organic materials into their sulfate salts permitting estimation of their total content as sulfates or oxides.

We also perform ash testing by ASTM D482ASTM D874DIN 51575IP 4, and ISO 6245. These different test methods use different instruments or procedures or are used for certain sample types. Click on the test method number to learn more about each test.
