Samples of controlled pore glass were used as model materials for comparison of pore distributions obtained by low temperature nitrogen adsorption/desorption and by mercury porosimetry. Pore distributions calculated from nitrogen sorption data by means of Broekhoff and de Boer equations seemed to be more reliable than results based on Kelvin equation or those obtained by mercury porosimetry, since the latter predict too narrow pores.
