Abstract. Certain quartz crystal plates are frequency sensitive to mass loading when operated in particular modes of vibration. Frequency can currently be measured with a precision as high as one part in 10 10 in as short a time as one second so that dynamic measurement of extremely small mass changes can be made. Further, the resonant frequency is a function of temperature gradients within ...
