Quartz Crystal Microbalance (QCM)
*Sensor = Quartz Crystal with electodes.
* Tuned oscillator with frequency inversely proportional to mass between electrodes plus mass on them.
* Follows the Sauerbrey Equation:
change in frequency,
deltaf= (-2.26
x 10-6cm2g-1s)(initial frequency)2(change
in mass)
* Experiment
