adsorption delay Delayed take up of water vapour by the cargo. This usually refers to water vapour and describes the fact that during the day the water vapour is given off by the cargo to the air in the container (desorption) faster than the cooling of the container air is introduces water vapour to the cargo (adsorption). The water vapour condenses on the walls of the container thus leading to damage.
