Liquid membrane ion-selective electrodes for potentiometric dosage of coper and nickel [PDF]
Journal of the Serbian Chemical Society, 2005 This paper presents experimental and theoretical data regarding the preparation and characterization of three liquid-membrane electrodes, which have not been mentioned in the specialized literature so far. The active substances, the solutions of which in

TrAC Trends in Analytical Chemistry, 2008 Potentiometric sensors share unique characteristics that set them apart from other electrochemical sensors. Potentiometric nanoelectrodes have been reported and successfully used for many decades, and we review these developments. Current research chiefly focuses on nanoscale films at the outer or the inner side of the membrane, with outer layers for ...

Angewandte Chemie International Edition, 2007 AbstractFor most chemists, potentiometry with ion‐selective electrodes (ISEs) primarily means pH measurements with a glass electrode. Those interested in clinical analysis might know that ISEs, routinely used for the determination of blood electrolytes, have a market size comparable to that of glass electrodes.

Active Potentiometry for Dissolved Oxygen Monitoring with Platinum Electrodes
Sensors, 2018 Potentiometric oxygen monitoring using platinum as the electrode material was enabled by the combination of conventional potentiometry with active prepolarization protocols, what we call active potentiometry. The obtained logarithmic transfer function is
