Abstract: Provided herein are techniques for identification of viable and nonviable cells in a cell culture that include measuring a resonance impedance spectral response of at least one resonator in proximity to the cell culture and correlating the measured response to the concentration of viable cells in cell culture and/or the concentration of nonviable cells in cell culture.

Abstract: A system includes a vessel system for a fluid, a sampling assembly and a resonant sensor system coupled to the sampling assembly. The resonant sensor system may include a subsystem that detects a set of signals from a resonant sensor system at a plurality of locations in the vessel. The resonant sensor system may also include a subsystem that converts the set of signals to values of a complex impedance spectrum for the plurality of locations and stores the values of the complex impedance spectrum and frequency values. A subsystem determines a fluid phase inversion point from the values of the complex impedance spectrum.

Abstract: A sensor includes a resonant transducer, the resonant transducer being configured to determine the composition of an emulsion. The composition of the emulsion is determined by measuring the complex impedance spectrum values of the mixture of the emulsion and applying multivariate data analysis to the values.
