Cubis® II: Residue on Ignition

Last updated: April 2021

Overview

Residue on Ignition is a backweighing application used to determine the ratio of inorganic and organic components in samples. The testing procedure can be used for a wide range of sample types to determine inorganic impurities in organic substances, or vice versa.

Samples are subjected to heat treatment in a drying oven under the influence of oxygen, which destroys organic substances. The loss of mass (i.e., loss on ignition) represents the organic portion of the sample while the residual ash (residue on ignition) represents the inorganic portion.
