Abstract

PURPOSE: To achieve high performance and long life, by forming the sensing film of the cation concentration selective electrode to measure the cation concentration in scrum with the close adhesion of the inner and outer films of macromolecular material scattering the fourth class ammonium salt.
CONSTITUTION: In the cation selective electrode to measure the cation such as chlorine ion present in the body liquid such as scrum, the sensing film is formed with close adhesion of the inner film scattering 20W25% of the fourth class ammonium salt to the polyvinylchloride and the outer film scattering 5W30% of the quaternary ammonium salt to synthetic resin. As the quaternary ammonium salt, 3-methyltrioctylammoniumchloride having 1W4 or alkyl radicals of C7W14, is used. As the outer film, the film taking methyl methacrylate as major constituent and having 1015W1019Ω/cm and 3.0W3.7F/m of dielectric constant is most suited.
