| Phospholipase activity was determined by potentiometric titration according to the method of De Haas et al. |
| The calculation of hydrogen ion concentrations, using this formalism, is a key element in the determination of equilibrium constants by potentiometric titration. |
| Potentiometric technique was used to determine the soil pH by a pH meter. |
| The imaginary surface defined by the stable, or static, water levels measured in wells completed in a confined aquifer is called the potentiometric surface. |
| With the potentiometric method, no CA activity could be measured, whereas with the isotopic disequilibrium technique, significant CA activity could be detected. |
| The acid number measurements were performed in a potentiometric titrator, model 877 Titrino plus. |
