Abstract
A gas purifier having a removeable sample canister apparatus and gas adsorber in combination is provided for use in atmospheric containment and cleanup systems in nuclear power plants and other air and gas filtering applications. The sample canister is particularly adapted for removeable attachment to and use in combination with a gas adsorber having a plurality of parallel spaced filter beds. The sample canister is designed to permit the sampling of adsorbent material at discrete time intervals without disturbing adsorbent material in the filter beds and without disturbing the structural integrity of the gas adsorber to which the sample canister is attached.
