Adsorption measurements belong to the primary characterization tools used to determine the textural properties of porous solids such as Brunauer–Emmett–Teller (BET) area, pore volume, and pore size distribution as well as to estimate the energy of host–guest interactions. Accurate description of gas sorption in metal–organic frameworks (MOFs) is crucial for evaluating their performance and provides key insights into textural properties such as adsorption capacity, pore volume, and pore size distribution. This tutorial paper aspires to provide a practical guide for graduate and undergraduate students, as well as researchers who are new to the field, on low-pressure gas adsorption measurements (up to atmospheric pressure). Key aspects such as sample preparation, activation strategies, adsorption measurement techniques, data analysis, and reporting are discussed in detail. We believe that this Tutorial could serve as an entry-level teaching resource for gas sorption measurements in MOFs.
