Active Potentiometry for Dissolved Oxygen Monitoring with Platinum Electrodes

open access: yesSensors, 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

Nanoscale potentiometry [PDF]

open access: yesTrAC 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 ...

Modern Potentiometry [PDF]

open access: yesAngewandte 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.

A method for the determination of the dissociation constants of acids with an uncalibrated glass electrode [PDF]

open access: yes, 1975
A method is presented for the determination of absolute pKa values of acids in solvents with a high dielectric constant by potentiometry with an uncalibrated glass electrode; in the determination, the glass electrode becomes calibrated.
