Quartz Crystal Microbalance as a Sensor to Characterize Macromolecular Assembly Dynamics

Figure 8

The configuration used where the quartz, shown by the open bottom rectangle, is treated as rigid and the effects of the load above it are summarized as changes in the spring constant and dashpot to the left of the quartz. Recall that the QCM under investigation is shorted. Therefore, the shunting impedances are shorted out and can be neglected.
