Three Zero-Length Column (ZLC) systems are available. They allow for the rapid screening of small quantities (1-5mg) of solid adsorbents. The experiment can measure the kinetic of adsorption as well as the equilibrium uptake. Exposure to water vapour and other flue gas contaminant (i.e.: SOₓ and NOₓ) and their effect on the stability of porous materials can also be tested in these systems.
