The automatic adsorption apparatuses (BELSORP-mini, BELSORP-18plus, BELSORP BG) have been developed in order to measure adsorption isotherms for single gas and binary mixed gases. In BELSORP-mini, the new methods of measuring the dead volume (V<SUB>d</SUB>) and saturation vapor pressure (P<SUP>0</SUP>) are adopted; namely, both of V<SUB>d</SUB> and P<SUP>0</SUP> are measured at each point of the adsorption isotherm of nitrogen gas at 77 K. As a result, the reliability of the N<SUB>2</SUB> isotherm increases. In BELSORP-18plus, the adsorption of vapor on the inner-wall of the apparatus is taken into account in determination of the isotherm of vapor. In BELSORP BG, a combination of gravimetry and volumetry is adopted in determination of the isotherms for binary mixed gases. The adsorption data obtained from both methods make it possible to determine the individual isotherm of each constituent gas without chemical analysis.
