Abstract

PURPOSE: To prolong the life of electrode and also, to improve the stability of measurement, by specifying the viscosity of polyvinyl chloride formed of the inductive membrane of ion selective electrode.
CONSTITUTION: After an ion inductive membrane 1 is melt-stuck to the end part of a body 2, an inner reference solution 3, for example, 10-2M sodium chloride solution is filled up in the body 2 and silver-silver chloride electrode rod is inserted into said solution as an inner reference electrode 4 and then, a leading wire 6 is taken out from the electrode 4 through the cover 5. Viscocity of polyvinyl chloride used as the base body of the membrane 1 is made to be 0.85W1.15. Hereby, life of ion selective electrode is prolonged and stability of measurement can be improved.
