Hydrogen Analyzer Based on Coulometric Titration Using Proton Conductive Solid Electrolyte

A Coulometric-Titration Coulometer

A highly precise coulometer is described which permits time integration of currents totaling 100 coulombs or more with a precision of about 1 part in 100,000. The current to be integrated oxidizes hydroquinone in an electrolysis cell, producing quinone and acid. The quinone is t hen reduced by constant-current coulometric titration, the end point being indicated by hydrogen-ion concentration me...

An all solid-state electrochemical electrolyte analyzer.

Ion-selective electrodes have been applied to analysis of blood electrolytes with some success. However, currently available ion-selective electrode systems tend to be elaborate and expensive. We describe a clinical electrolyte analyzer in which inexpensive ion-selective electrodes are used. The elec‘trodes are in the configuration of thin wires and are all solid in construction. They may be di...

Coulometric titration of D(+)-glucose using its enzymatic oxidation.

A definitive method is described for the indirect assay of milligram quantities of D(+)-glucose by coulometric titration. D(+)-Glucose was aerobically oxidized by glucose oxidase in an acetate buffer solution (pH 5.1). Subsequently, the enzymatically formed hydrogen peroxide was titrated coulometrically with electrogenerated hypobromite in sodium bromide-sodium tetraborate medium of pH 8.6, wit...
