| abstract |
The invention relates to a reference electrode for the potentiometric measurement of ion concentrations, comprising at least one swellable polymer body filled with at least one electrolyte salt and a type-two arrestor element, preferably of the Ag/AgCl type, is present in the polymer body, the polymer body being preferably constituted of organic, hydrophobic prepolymer segments which are three-dimensionally cross-linked to one another by preferably organic, hydrophilic polymer chains. |
