Abstract

An application of blocking layers between sample and electrodes permits to avoid the influence of electrode polarization and opens new opportunities in DRS investigations of the conductive systems, such as polysaccharides and proteins containing water and electrolytes. The proposed methodical approach is applied for plate capacitor type of the cell and for the one in coaxial lien for the measurements in the frequency region 0,1 Hz-10 MHz and 1 MHz-1GHz respectively, using Novocontorl GmbH equipment. The possibilities to investigate an evolution of the biological system in time and temperature scale avoiding the influence of electrode polarization are demonstrated.
