Application Overview

Porous carbon materials have a vast range of industrial applications. The selective adsorption displayed by activated carbons, in the form of carbon molecular sieves (CMS), is exploited in a number of filtration and separation processes, including air filtration, gas separation, volatile organic compound (VOC) filtration and solvent recovery, and water treatment.

Hiden Isochema products have been used widely to characterise the pore structure and the adsorption properties of activated carbon materials in both academic and industrial research organisations. Most of our products can be used for the characterisation of these materials, with IGA-003 and IGA-200 being particularly powerful for multicomponent gas and vapour sorption measurement.

Examples of published data measured using Hiden Isochema instrumentation can be found in the reference list below.
