This overview discusses the fundamental principles and evolving methodologies employed to characterise moisture sorption isotherms and thermodynamic properties in a diverse range of materials.

An important method used to characterize porous materials is measuring gas and vapor sorption. The uptake capacity is yielded directly by isotherms, which can be used to measure the suitability of ...

THE various well-known theories of gas-liquid chromatography all assume a linear ‘partition’ isotherm, that is, the concentration of a solute in the stationary liquid phase is a linear function of the ...

In the IMB method, a mass spectrometer (MS) is used to determine the gas composition at the outlet after a controlled gas mixture passes over a sample suspended from the IGA microbalance. The partial ...
