DYNAMIC ABSORPTION AND DESORPTION OF MOISTURE EVALUATION APPARATUS DYNAMIC ABSORPTION AND DESORPTION OF MOISTURE EVALUATION METHOD AND DYNAMIC ABSORPTION AND DESORPTION OF MOISTURE EVALUATION PROGRAM

摘要

An apparatus, a method and a program for evaluating dynamic absorption and desorption of moisture capable of broadly analyzing the characteristics of a sample are provided. The water vapor concentration in the test gas in a measurement chamber in which the sample is placed is adjusted and the water content in the sample in the measurement chamber is measured by a measurement unit. When the concentration of water vapor in the test gas in the measurement chamber is changed, the deviation B of the change in the water content in the sample measured by the measuring unit with respect to the change in the water vapor concentration is calculated. The deviation B of the change in the moisture content in the calculated sample corresponds to the adsorption/desorption speed in the sample. Therefore, not only the moisture content of the sample but also the adsorption/desorption rate can be analyzed, so that the characteristics of the sample can be widely analyzed.
