摘要： A sodium ion sensor having a composite electrolyte is disclosed. The sodium ion sensor has an outer electrolyte which is insensitive to water and has a high transport activity for sodium ions and an inner electrolyte which is a thin membrane having a very high sodium ion selectivity. The sodium ion sensor having such an electrolyte is sensitive only to the transport of sodium ions and may be operated in aqueous solutions without buffering and in the presence of other alkali ions and alkaline earth metal ions. Sensors of this type operate in EMF mode to give a substantially instantaneous determination of the sodium ion concentration of the aqueous medium being analyzed. The sensor may be used as an on-line sensor directly exposed to the medium to be analyzed.
