Material amount measurement method, pore size distribution derivation method, substance amount measurement device and pore size distribution derivation device

摘要

PROBLEM TO BE SOLVED: To provide a method for measuring an amount of material, a pore size distribution deriving method, a device for measuring an amount of material and a pore size distribution deriving device whereby it is possible to derive an amount of material adsorbed or condensed on a porous sample and a pore size distribution of the porous sample with simplicity and versatility.SOLUTION: A method for measuring an amount of material includes supplying a mixture of an uncondensable gas and a condensable gas to a porous sample while changing the relative pressure of the condensable gas, and measures by FT-IR an amount of material for the condensable gas adsorbed or condensed on pores of the porous sample.SELECTED DRAWING: Figure 1
