Abstract The results of surface structure investigations involving the use of thermoporometry and gas-sorptometry on porous glass, silica and a zeolite were compared. The most frequent and the mean pore width were found to be in accordance, but major differences in specific surface were observed. These two measuring methods complement each other, because with gas adsorption a dry sample is investigated, while with thermoporometry a sample immersed in a liquid is investigated. The probe molecules (nitrogen or noble gas and water or benzene, respectively) differ in size. The features of the two methods are discussed.
