The behavior of quartz crystal microbalance in high pressure CO2

Kwangheon Park; Moonsung Koh; Chunghyun Yoon; Hakwon Kim; Hongdoo Kim

Abstract Quartz crystal microbalance (QCM) is a very useful in situ tool for measuring minute changes of mass of thin surface films with real-time monitoring. The effect of temperature deviation and pressure change, viscosity and roughness loading on the frequency shift were examined by measuring the frequency change of bare QCM under high-pressure CO 2 . From a contour analysis, the frequency shift from viscosity loading and that from roughness loading were obtained. Frequency shift from viscosity loading was about three to four times larger than that estimated by Kanazawas equation. The resonator, whose surface roughness was larger than the diffusion length, exhibited a frequency shift from roughness loading.
