Abstract :
Application of quartz tuning fork resonators to high throughput gravimetric measurements is described. It is demonstrated that tuning fork resonators can be successfully used for accurate measurement of mass in the tens-of-micrograms range without incurring restrictions on sample shape, size, mechanical properties or sample adhesion and position on sensor surface. Experimental results on sensor calibration and weighing small samples of materials are presented.
