SOLID STATE ELECTRODE FOR THE DETERMINATION OF SODIUM ION CONCENTRATIONS IN SOLUTIONS

摘要

A solid state electrode for the determination of sodium ion concentrations in solutions, with a solid state electrolyte having a high conductivity for sodium ions being provided as the sodium sensitive membrane. The solid state electrode and a reference electrode forms a sensor. The advantages of the sensor of invention are, in particular, high selectivity combined with economical production in thick-film technology. The sensor may be constructed in cylindridcal form.
