ozone is dissolved ozone in a liquid cryogen. A container containing a liquified cryogen is provided. A gaseous stream of ozone is allowed to flow into at least one adsorption unit containing an adsorbent material, thereby adsorbing ozone thereupon. The cryogen is allowed to flow from the container to the at least one adsorption unit and therethrough thereby extracting an amount of the ozone adsorbed upon the adsorbent material, wherein the cryogen is in either a liquid, gaseous or supercritical phase as it flows through the adsorption unit. ozone becomes dissolved in the cryogen.
