Abstract: Technical equilibrium can be used to measure a single gas isotherm in a relatively fast and continuous manner rather than, for example, in a batch manner. Further, an expansion vessel can be used for successive desorption a multicomponent gas in combination with determining the composition of the multicomponent gas in combination with a calculation that provides both qualitative and quantitative information about the multicomponent gas. Moreover, a multicomponent gas can be flowed through an adsorbent bed and the and the flow of the multicomponent gas flow is shut off and isolated when equilibrium is reached.
