Quartz Crystal Microbalance Sensor

Surface Preparation/Characterization, Stanford University

The quartz crystal microbalance (QCM) sensor has recently been put into place in the Stanford CPIMA Shared Facilities and is experiencing a surge of use. This sensor is extraordinarily sensitive to mass changes associated with the deposition of material onto the surface of a quartz crystal. These changes are sensed as changes in the natural resonant frequency of the QCM.
Four Sensors on site.
Models include a Q-Sense D300 analyzer, a Q-Sense E4 QCM-D multichannel analyzer, and a Maxtek RQCM analyzer.
