ABSTRACT:
Embodiments of the invention contemplate an apparatus that determines gas sorption properties of a large number of material samples simultaneously, by sequentially measuring the pressure in a plurality of sample chambers until all chambers have reached equilibrium pressure. In most applications, it is most useful to quantify the sorption capacity of a material under specific conditions, i.e., at a certain temperature and pressure. Because sorption capacity is determined by bringing a material sample to an equilibrium state with a dosing gas, detailed kinetic data related to the sorption properties of a material are not absolutely necessary. Therefore, complete pressure-time curves are not typically necessary, and only the equilibrium pressure of a material sample for a given quantity of dosing gas is required.
