Electrical Impedance Spectroscopy - a powerful tool of investigation

The Electrical Impedance Spectroscopy (EIS) method can be used to characterize materials (e.g. to determine the dielectric constants) and/or to study the dynamics of physcial processes where dielectric constant is involved.

In this work we show the measurement technique and an example for characterizing the sample of UHQ water. The measurements are made having as reference the empty measurement cell. Having a physical process (e.g. water evaporation, or penetration into a porous material) the EIS can be successfully used to characterize its dynamics [1].
