1. A method, comprising:
receiving, by a device, measurement data associated with a measurement subject;
determining, by the device, an adsorption isotherm for the measurement subject based on the measurement data;
determining, by the device, a thermodynamic adsorption capacity of the measurement subject based on the adsorption isotherm, wherein the thermodynamic adsorption capacity is different from a geometric adsorption capacity;
determining, by the device, a thermodynamic surface area value associated with the measurement subject based on the thermodynamic adsorption capacity; and
providing, by the device, an output based on the thermodynamic surface area value associated with the measurement subject.
