| titleOfInvention | PROCESS FOR THE PRODUCTION OF REFERENCE ELECTRODES |
| abstract | 1. A process for the preparation of reference electrodes based on silver / silver halide in saturated alkali halide electrolyte for potentiometric measurement and analysis methods, in particular for pH and redox potential measurements, measurements with ion-sensitive electrodes and for potentiometric titrations, in the temperature range 0 to 150 degrees C. and / or under severe thermal cycling, which is also suitable as a non-polarizable reference system for polarographic, amperometric and similar under current load measuring and analysis methods, characterized in that a significant portion of the silver halide used to prepare the electrode is reduced to silver with a suitable reducing agent and in that the resulting silver halide / silver mixture in one or more layers of optionally different silver content on an electrode base of silver or silver plated electrochemically inert n material melts. 2. A process for the preparation of reference electrodes according to claim 1, characterized. that as a suitable reducing agent, preferably hydrazine or hydroxylamine or formaldehyde is used. A method for the production of reference electrodes according to claim 1 and 2, characterized in that on the electrode base, a layer of the partially reduced silver halide with a reduced silver content of at least 40 mole percent is melted. .. |
