| Resumen: | Routine pH measurements are carried out with pH meter-glass electrode assemblies. In most cases the glass and reference electrodes are thereby fashioned into a single probe, the so-called ‘combination electrode’ or simply ‘the pH electrode’. The use of these electrodes is subject to various effects, described below, producing uncertainties of unknown magnitude. The multi-point calibration is a useful tool to characterise the performance of pH electrodes. This is demonstrated with different commercial pH electrodes. |
