Extractions & Digestions

Chemical & Thermal Digestion

Dissolution of sample matrix with either strong acids or bases, or high temperatures.

Applications:

Determination of filler content by digestion of matrix resin

Acid, base, and thermal destruction of the matrix can be performed

Work We've Done

Epoxy Composite

A client had several samples of epoxy composite for reinforcement content determination.

The samples were weighed and the epoxy digested in a mixture of hot sulfuric acid and hydrogen peroxide. The insoluble reinforcement was filtered, rinsed, dried and weighed, and the reinforcement content was calculated.
