Complex Electromagnetic Conductivity of Liquids

Liquids, forming the base of our life, are giving us more and more troubles. Studying and controlling electrodynamic properties and processes in liquid substances opens new possibilities for understanding and using liquids. The article presents the concept of using the complex electromagnetic conductivity (CEC) for describing and studying liquid properties.

Any liquid can be described as a composition of communicating and moving ions, micro and macro currents, static and dynamic electromagnetic fields, which all together directly determine main characteristics and properties of every concrete liquid.

Finding and describing direct and single-valued multiple correlations between physico-chemical and electrodynamic parameters of different liquids can significantly enlarge our knowledge and possibilities within many leading directions of science and technology
One of the most promising ways here is describing liquid with its CEC, including active and reactive components for electric and magnetic fields within wide frequency range.

Known liquid conductivity measurements are mostly using only its active electrostatic component, while reactive and especially magnetic conductivity can provide much more information on practically every liquid parameter.

DVM has created a special CEC measuring sell (fig.1.), allowing to perform a wide range of various liquids investigations. The tested liquid is placed here into the controlled source of both electrical and magnetic fields on different measuring frequencies with the possibility to indicate the corresponding liquid respond.

The sell is monitoring the following main parameters: Relative active component of liquid conductivity, Relative liquid capacitance and liquid Hall-resistance.

All above parameters depend on the concentration and mobility of different ions in the liquid and also on the concentration and mobility of different dipoles in the liquid, allowing, within the tested frequency range, to obtain the complete information on practically any substance present in the tested liquid composition.
First investigations show the possibility to trace the liquid parameters with extremely high accuracy, especially it appeared possible to evaluate and controll the process within liquid magnetic conditioning systems.

Some possible application areas:
Continuos water quality monitoring in artificial and natural reservoirs. Control over water purification processes for consumption and industrial needs
Liquid properties control in chemical and power engineering. Chemical processes and liquid fuel efficiency increase
Diagnostics and controlled therapy on biological liquids (blood…). Liquid medicines efficiency increase
Continuous monitoring and liquid purification control in agriculture and food industry
