For each data point measured during an adsorption experiment, data related to the equi- desorp amount amount adsorbed during the desorption measurement (float, mol kg -1 ) librium pressure, saturation pressure and amount adsorbed can be stored. Importantly, these should be stored in units of pascal and mol kg -1 to follow the IUPAC recommendations. The saturation pressure can be recorded for each data point, as we have discovered that some instruments will report this value for every point.
