ABSTRACT:
The invention provides a method, a system, and a computer readable medium for determining the fill-ready status of one or more wells of a plurality of wells formed in a filter or solid-phase extraction (SPE) plate. In the method, a signal is directed toward a well of the plurality of wells. A reflected signal is received from the well responsive to the directed signal. The fill-ready status of the well is determined based on the received reflected signal. The steps may be repeated until the fill-ready status of each of the plurality of wells has been determined. In the method and the apparatus, the directed signal may be generated by a piezoelectric crystal. Some of the reflected vibrations impact the piezoelectric crystal, which oscillates in response. The piezoelectric crystal transmits a signal to a processor, the signal corresponding to the height of the liquid or other material in the well.
