Materials Testing: Liquid Materials

Application Notes

There are increasing demands for the electrical measurement to investigate the properties of liquid materials that is characterized by permittivity and conductivity.


Permittivity, also called as dielectric constant is related to the electric polarization and conductivity is the measure of a material’s ability to conduct electric current when applied an electrical field. Dielectric spectroscopy, also known as electrochemical impedance spectroscopy (EIS) measures permittivity and conductivity as a function of frequency. Complex permittivity measurement enables not only to evaluate electrical property but also to analyze the composition, the structure of the heterogeneous system and the interaction of the molecules in the liquid.
