1. An impedance-based method for detecting microbial growth, the method comprising:
providing a vessel with at least two electrodes disposed therein;
introducing a sample to be monitored for microbial growth in the vessel, the vessel having a volume of at least 10 mL, wherein the electrodes are immersed in the sample;
measuring total impedance of the sample to determine a total ionic composition of the sample over time;
from the measurement, determining an imaginary reactance component of the total impedance over time;
determining changes in the imaginary reactance component over time; and
from the determination of the changes in the imaginary reactance component over time, determining whether microorganism growth has occurred.
