To provide a highly accurate and speedy method for measuring a gas adsorption amount with using a highly sensitive direct measuring means for a gas concentration by a GC(gas chromatography), a GC-MS(gas chromatography and mass analysis), an IC(ion chromatography), a gas detection pipe, etc.
According to this method for measuring an adsorption amount, an adsorption performance of an adsorbent to a specific gas is evaluated. An initial concentration of a gas to be measured and a residual concentration of the gas after reaching an adsorption equilibrium with the adsorbent are measured in a sealed container keeping a predetermined condition of a temperature and a relative humidity. In this case, the temperature and relative humidity are in a range of 5-60°C and 95%, respectively. A means for keeping the relative humidity is an aeration.
