The results of measurement showed that anomalous breakthrough curves were observed at -180C which is effect of condensation of noble gas. However, the amomalous breakthrough curves was not observed at -170C. It was shown that the activated good performances. The effect of materials propertied on the absorption and the desorption properties is summarized as follows: The longer breakthrough time and the steeper break through curves were obtained as the grain size became smaller and the specific surface area gets larger. Further studies are needed to elucidate effect on enrichment of experimental conditions by varying such as the heating rate,sweep gas velocity,and the onset tempertuer of heating
