Abstract

A water vapor concentration in a test gas in a first space of a measurement space in which a sample is disposed is adjusted, and a water vapor concentration in a carrier gas in a second space separated from the first space by the sample is measured by a measurement unit. When the water vapor concentration in the test gas is changed, a shift B in change of the water vapor concentration in the carrier gas from the change of the water vapor concentration in the test gas is calculated. The calculated shift B in the change of the water vapor concentration in the carrier gas corresponds to ease of moisture accumulation in the sample. Thus, it is possible to analyze not only the amount of moisture permeating the sample but also the ease of moisture accumulation, so that characteristics of the sample can be widely analyzed.
