Abstract: A set (1) comprising at least two ion-selective solid-contact electrodes comprises at least two ion-selective measuring points (6). Each measuring point (6) comprises a metal conductor (3) and/or an inner layer (7) of a conductive polymer and an outer, ion-selective membrane (8). At least two measuring points (6) are selective in each case with respect to a different ion of an analysis solution. One of the solid-contact electrodes can be used as a reference electrode.

Abstract: The invention relates to a process for storage of a pH glass electrode (1), characterized in that at least the swelling layer (2) of the pH glass electrode (1) is stored in a storage solution (3) which is essentially free of alkali-metal ions. Preferably the storage solution (3) is an ammonium chloride or ammonium nitrate solution (NH4Cl solution or a NH4NO3 solution), or an alkaline earth salt solution, especially an alkaline earth chloride solution, preferably a magnesium chloride solution (MgCl2 solution).
