A technique to measure the adsorption characteristic of surface area and pore size of a ceramic thin film is proposed, and its performance is examine. The thin film is fabricated directly on the resonator surface to measure the adsorption capacity of the film as it is, and using carbon dioxide makes the measurement easy. The results indicates that the measured surface area is satisfactory, while the pore size has some error. It is suggested that readily available carbon dioxide can be used to determine adsorption capacity of thin film at room temperature.
