Storage solution for pH glass electrode

摘要

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).
