Abstract

A new device for measuring the pore characteristics of adsorbents is developed for fast measurement and convenient sample handling. The proposed device utilizes a quartz crystal resonator capable of detecting the change of mass loading in nanogram scale. The measured material is coated on the electrode surface of the resonator, and the change of resonant frequency of the resonator at different pressures of adsorbate gas is converted into the adsorbed_x000D_ amount used in the computation of the adsorption surface area and pore size. For the performance evaluation of the device, alumina and activated carbon are tested with the adsorbate, i-butane. The experimental results show that the proposed device gives comparable measurements with some deviation to the reference values of the adsorption characteristics. It is proved that the device is relatively simple and requires short measurement time and the mild condition of sample handling.
