Abstract: An electrochemical reference electrode for use in ion potential measurements of solutions. The liquid junction structure of the electrode comprises a hydrophobic polymer having a suitable salt distributed therethrough and held in place to prevent leaching by a filamentary structure of the polymer. The liquid junction structure is a diffusion membrane material and permits ionic communication between the salt bridge solution of the electrode and the sample solution essentially by means of diffusion, rather than by liquid flow. The entire electrode body may be made of the polymeric material. The electrode is particularly suited for process applications.
