MANUFACTURE OF ELECTROCHEMICAL ELECTRODE AND ITS LIQUID JUNCTION

摘要

PURPOSE:To obtain an extremely small electrochemical reference electrode whose liquid junction diameter at the tip of the electrode applicable to a very small electrolyte cell is extremely small. CONSTITUTION:A fine tube 13 is integrally formed at the lower end of a main body glass tube 1 whose inner diameter is equal to an outer diameter of a lead terminal 6, and a heat-resistant fine fiber is provided in the fine tube 13 to prevent electrode solution 4 from leaking to provide a liquid junction 2 applicable to a very small electrolyte cell, while the lead terminal 6 is directly connected to the main body glass tube 1 to make a reference electrode extremely small.
