SENSITIVE MEMBRANE FOR ION SELECTIVE ELECTRODE

Title:

SENSITIVE MEMBRANE FOR ION SELECTIVE ELECTRODE

Document Type and Number:

WIPO Patent Application WO/2011/007384

Kind Code:

A1

Abstract:

A sensitive membrane for an ion selective electrode, which is selectively reactive with Na+ ions. The sensitive membrane for an ion selective electrode is characterized by containing an ionophore, an anion excluder, a plasticizer and a base material, with the ionophore content being 85-95% by weight relative to the total amount of the ionophore and the anion excluder.
