Abstract
In this study, the possibilities of applying quartz crystal microbalance (QCM) method in pulsed mode for investigating the adsorption dynamics of volatile compounds on finely dispersed sorbents is shown. The use of piezoelectric quartz resonator (PQR) sensors with chemical coverings on the base of metal stearates or thiolates, as well as other low-inertia sensors is proposed to evaluate the concentration of gas-phase sorbate current in the flow cell of electronic nose-type sensors. These sensors are placed in the cell in parallel to the PQR with a sorbent under investigation.
