Reference-Electrode Free pH Sensing Using Impedance Spectroscopy [PDF]

, 2018
We present a reference-electrode free sensor able to measure both pH and conductivitybased on impedance spectroscopy. The electrode is made of a layer of indium-tin-oxide (ITO).

An Application of a Porous Charcoal Junction to a Reference Electrode in Acidic and Alkaline Solutions

Electrochemistry, 2020
Charcoal is used as a salt bridge at the end of the Ag/AgCl reference electrode in acid and alkaline solutions. The impedance and the phase shift of the Ag/AgCl wire with the use of the charcoal junction are stable in all solutions, while those with the ...

STABILITY POTENTIAL OF THE LEAD-ANTIMONY ELECTRODE REFERENCE ELECTRODE

, 2022
The aim of the work was to investigate the stability of the potential of the lead-antimony reference electrode. The possibility of selective dissolution of antimony from lead-antimony alloy and its effect on the reference electrode potential was ...

Strategies of Miniaturised Reference Electrodes Integrated in a Silicon Based “one chip” pH Sensor

Sensors, 2003
Different types of Ag/AgCl reference electrodes have been realised by means of thin- and thick-film technique. For inner electrolyte, KCl-containing membranes have been deposited and different coatings have been used to protect the reference electrode ...

Corrosion Sensor for Monitoring the Service Condition of Chloride-Contaminated Cement Mortar

Sensors, 2010
A corrosion sensor for monitoring the corrosion state of cover mortar was developed. The sensor was tested in cement mortar, with and without the addition of chloride to simulate the adverse effects of chloride-contaminated environmental conditions on ...

Instantaneously usable screen-printed silver/silver sulfate reference electrode with long-term stability

Electrochemistry Communications, 2019
We developed an instantaneously usable screen-printed silver/silver sulfate (Ag/Ag2SO4) reference electrode with long-term stability. The reference electrode was composed of a Ag layer, a Ag/Ag2SO4 layer, an inner electrolyte layer, and a liquid junction
