Applications of an effect based on electromagnetic field-matter interactions for investigations of water

Abstract

A possibility for developing a new method for investigating liquids, water in particular, based on the Surface Photo-Charge Effect has been demonstrated. Due to the strong susceptibility of this effect to the state of the irradiated interface, upon illumination of the interface an easily measurable electric signal arises with magnitude depending on the properties of the liquid. This signal, if properly calibrated, can serve as an express contactless inspecting tool. A variety of sensors for water quality control can be developed using this method. Some examples of the presented experimentally tested sensors based on the effect are for quality control of the chemical composition of water, registering processes in liquids and level sensors. © 2013 Springer Science+Business Media Dordrecht.
