Electrochemical Impedance Spectrometer

General Description

The CYBRES MU (Measurement Unit) is a compact device for differential electrochemical impedance spectroscopy (EIS) with two and four electrodes in the low frequency range. The device is able to perform accurate differential measurements in the time and frequency domain, comparing the properties of two liquid or organic samples. Such a task arises in applications where weak ionic, electrochemical or electrophysiological dynamics should be recorded and analysed in real time in vivo and in situ. This EIS meter is capable of performing excitation spectroscopy by optical or electromagnetic means. In addition to spectral, correlation and regression analysis, the signal scope mode is also suitable for fast distortion analysis. The system has been developed for single  measurements or for long-term monitoring, also with graphical online output on the web. The electrochemical measurement system is a finalist of the EC innovation conpetitions 2016, 2019.

Applications

General applications are precise industrial fluidic measurements and differential fluidic meters in research/laboratory usage, detectors of weak electromagnetic and non-electromagnetic emissions by analysing electrochemical changes in fluids. Since the liquid samples are protected from temperature variations and electric fields, the device is suitable for the analysis of electrochemical properties by non-chemical, non-temperature, non-acoustic, non-mechanical and non-electromagnetic impacts on the sample liquids. Impacts of such factors can be investigated also during the experiment. These measurements are characteristic for analysis of weak interactions, in particular in research of certain quantum effects appearing in macroscopic systems. The device allows statistically significant measurements of these effects with the standard EIS method. The MU EIS system is also designed for long-term monitoring of liquids and organic tissues, e.g. for quality control purposes, in the analysis of biochemical reactions, long-term monitoring of fluid parameters at constant temperature conditions.
