Abstract
A gas purifier for impure gas is provided with a sensor of the end of useful life. The purifier has a housing completely filled with a gas sorbing material. The gas sorbing material is capable of reacting with the impurities contained within the impure gas. This reaction results in an expansion of the gas sorbing material which thereby causes the housing to expand. The purifier also has an impure gas inlet and a purified gas outlet as well as a strain gauge carried by the housing and means for determining the strain on the strain gauge thus determining the end of useful life of the gas sorbing material.
