Ash Content Analysis

Elemental Lab now offers ash content analysis. Ash content analysis determines the total amount of inorganic residue or ash that remains after a sample is burned at a high temperature. This technique is commonly used to analyse materials such as foods, polymers, coal and biochar.

The sample is heated to a very high temperature, 550 to 800 °C in a muffle furnace, over a set time (depending on the sample) to remove all moisture and volatiles (as vapour) and organics (as carbon dioxide and oxides of nitrogen). The sample is weighed before and after the ashing procedure to determine the percentage ash content.

Results in 5-7 business days from receipt of sample
