Continuous measurement of pH with the glass electrode II. Presentation of a new Needle-pH-electrode

pH Measurement with the Glass Electrode and Vacuum Tube Potentiometer.

Development of the Glass Electrode and the pH Response

The glass electrode is the most commonly used device to access the pH of an aqueous solution. It attains highly accurate measurements via simple and well-established procedures. However, the reasons why the glass electrode potential scales with hydrogen ion concentration according to almost Nernstian potential values have been long-standing challenges to explain. Only in the past 50 years has a...

Blood pH measurement with the glass electrode; study of venous and fingertip blood.

BSERVATIONS MADE DURING the routine estimation of blood pH with the glass electrode noted that specimens of fingertip blood often tended to drift rapidly toward the alkaline side when exposed to air at 370 or showed a slower drift in this direction under oil. This change was noted to be slower with specimens of venous blood. The pH of blood taken from fingertip or vein under oil and cooled rapi...

Equilibrium Potentials of Membrane Electrodes ( glass electrode / pH ) JUI

A simple thermodynamic theory of the equilibrium potentials of membrane electrodes is formulated and applied to the glass electrode for measurement of pH. The new formulation assumes the selective adsorption or binding of specific ions on the surface of the membrane which may or may not be permeable to the ion, and includes the conventional derivation based on reversible ion transport across me...
