摘要
Routine pH measurements are carried out with pH meter-glass electrode assemblies. The use of these electrodes is subject to various effects, described in this article, producing uncertainties of unknown magnitude. Therefore, the measurement of pH requires a suitable calibration by certified standard buffer solutions traceable to primary pH standards. This article addresses the optimal experimental procedure for the calibration problem to common pH meters, under D- and c-optimality criteria. The relevant calibration data analysis and the results are also presented in detail.
