“…100 kHz), which is assigned to the surface or charge transfer resistance and double-layer capacitance at the membrane/electrolyte interfaces. Finally, at the low frequency end, often a Warburg-type impedance signal is seen, which is due to the diffusion of ions within the membrane [1,4]. The semicircle owing to the surface resistance can be observed when the transfer rate of ions crossing the interfaces is limited by some mechanism [1].…”

The semicircle owing to the surface resistance can be observed when the transfer rate of ions crossing the interfaces is limited by some mechanism [1]. Investigations by EIS on valinomycin-based K þ -selective solvent polymeric membranes without added ionic sites [2] revealed that a resistive surface layer may build up between the membrane and the aqueous sample solution, thus contributing to a significant surface resistance [3].…”

The influence of lipophilic, electrically neutral surfactants added to the membrane on the ion transfer resistance between an aqueous sample and a polymeric ion-selective membrane has been studied by electric impedance spectroscopy and potentiometry. An increase in the surface resistance and a shift of the apparently super-Nernstian response to lower sample ion activities has been observed when using the nonpolar bis(2-ethylhexyl) sebacate as plasticizer.

“…The so-called coated-wire electrode is the simplest arrangement of a solid-state electrode [13,14], which led to the development of many potentiometric sensors of satisfactory response and selectivity. For this reason, preliminary studies on back-side contact microelectrodes were performed using a simple microsensor architecture, i.e., direct deposition of the ion-sensitive membranes on the surface of planar Au transducers.…”

“…Since the construction of coated-wire electrodes involves ill-defined mechanism of charge transfer between the membrane coating and the metallic transducer [13] an intermediate polyHEMA layer was applied in the microelectrode construction. This approach allowed introducing the internal electrolyte solution to the sensor structure, providing better potential stability of the electrodes, which was described in the literature for hydrogel-contact ionselective electrodes [16 -18].…”

This paper presents an overview of the studies carried out in the recent years in our laboratory, on the construction of different solid-state microelectrodes for flow-cell analysis. The microelectrodes were based on planar transducers made from a printed circuit board and manufactured as back-side contact structures, which facilitate their mounting in a flow-cell. Performances of the polymeric membrane ion-selective: coated-wire microelectrodes and microsensors with a polyHEMA layer containing internal electrolyte are compared. Conducting polymer -polypyrrole doped with ester of sulfosuccinic acid -was added to the PVC membranes to develop all-solid-state microelectrodes without internal electrolyte solution, exhibiting good potential stability in time. Finally, all-solid-state reference microelectrodes based on back-side contact transducers are prepared and examined. These structures were applied as reference electrodes in flow-cell measurements with potassium-selective planar microelectrodes.

Abstract. NASICON type ionic conductors can be used as the sensitive membrane of alkali ion sensors. The main advantages compared to the classical glass electrodes are the better selectivity and lower impedance. The mechanism of response of this type of ionic sensors is presented. The sensitivity results from a direct ionic exchange between the ceramic electrolyte and the solution which has been characterized by impedance spectroscopy. The origin of the selectivity in the NASICON framework is discussed in terms of structural and ionic exchange properties. The performance characteristics of sodium and lithium ion sensing devices are presented. Examples of biomedical applications such as the measurement of sodium concentration in the crevicular fluid and the determination of lithium in artificial serum are described.
