摘要
For making use of the whole working range of ion-sensitive electrodes, it is often preferred to measure the potentials at various concentrations in order to get a straight line of potentials versus logarithm of concentration. The numerical evaluation of the electrode parameters yields furthermore the statistical errors of these parameters. Using error propagation, it is possible to calculate the error in analysis caused by errors in calculation and measurement. Experimental details and results are given. © 1978 Springer-Verlag.
