“…Dielectric spectroscopy up to 100 MHz is usually performed with a capacitance chamber [13][14][15][16][17]. There, a sample solution is applied between the electrodes of a parallel plate capacitor and a frequency dependent impedance is measured.…”

“…The contributions (of polarization currents) due to the system of interest (e.g., polyelectrolyte, colloid) may be extracted only in the frequency range where they are of comparable or larger magnitude than EP effects. This practically limits dielectric spectroscopy below 100 MHz to studies of samples in electrolytes with I s not above 10 mM [13,14,16,17].…”

“…Dipole moments were obtained by measuring the dielectric constants of protein solutions via a capacitance cell connected to a HP4194A impedance analyzer through an Agilent 16047 D test fixture (Agilent Technologies, Palo Alto, CA) 14, 16. The cell's design is similar to that of Hollingsworth and Saville16 and Essex et al 20. (Fig.…”

“…Low-frequency frequency domain techniques to measure the complex permittivity of materials are often based on refinements [302][303][304] of sensitive methods for impedance compensation as originally designed as, for instance, Wheatstone [305,306], Wien [307], Schering [308], and Scheiber [309] bridge circuits. The principle of operation at the basis of all bridge methods is illustrated by Figure 54.…”
