Abstract
Provided is a method for liquid impedance measurement using a four-electrode device comprising an electrode structure. The method () comprises applying a sinusoidal voltage signal across a first outer electrode and a second outer electrode of said electrode structure and performing current and voltage measurements thereof. The method further comprises applying said sinusoidal voltage signal across a reference impedance and performing current and voltage measurements thereof. The method further comprises calculating an outer impedance between said first outer electrode and said second outer electrode based on a subset of the measurements. The method further comprises calculating an inner impedance between said first inner electrode and said second inner electrode a subset of the measurements, wherein the inner impedance represents the liquid impedance. A four-electrode device for performing the method is also provided.
