Sorption isotherms of methane at 308 K in unconditioned conventionally conditioned, and exchange-conditioned samples of TMHFPC (The original data were represented graphically)
Solubility, Solubility data series
Two methods of conditioning were studied. Conventionally conditioned isotherm were obtained with the samples which had been previously in contact with $\ce{CO2}$ gas under pressure of 6.2 MPa for 2—3 h with consequent pumping for two days. Exchange conditioning involves exposing samples to $\ce{CO2}$ gas and then sweeping it with a methane flux. For exchange conditioning runs a gravimetric technique was used. In two other types of experiments a pressure decay method was applied [1].
