Abstract :
It is desirable for QCM response time (time to measure a frequency change Δf) to be as short as possible, particularly for newer applications of QCM technology such as biochemistry, environmental monitoring for explosives, intrusion detection as well as a microbalance. A new method for making high resolution, rapid frequency measurements is described. The method is applicable for uncoated or functionalized crystals, as the application demands. For a 5 MHz crystal a conservative estimation time for a Δf of 0.1 Hz is less than 1 msec.
