Abstract

PURPOSE:To obtain a highly stabilized electrode, by isolating a sample solution from the inner liquid of standard electrode by a specific high molecular membrane. CONSTITUTION:A glass tube for calomel preservation 25 packed with calomel 7 and mercury 8 which is inserted with a platinum wire 9, and a diaphragm 24 made of a high molecular membrane which is attached to the tip end part of a protective tube 23 packed with aqueous solution of KCl 11 having a constant concentration, are arranged airtightly. The membrane 24 is made of the high molecular membrane having an inactive molecular structure not generting interfacial electric potential on the interface of the outer face contacting with a sample solution 3 by the ion seeds in the solution 3 or these activities, or not changing the potential even when the potential is gererated. For example, said diaphragm 24 is made of fluororesin, polystyrene resin, polyvinyl chloride dissolved by a solvent such as a high purity tetrahydrofuran and dissolved resin, afterwards, it is formed, the solvent is evaporated and the remain is dried up in a high purity inactive gas. Leakage or invasion is prevented perfectly because the aqueoue solution 11 in the tube 23 is isolated perfectly from the solution 3.
