1. A chloride selective electrode for detecting chloride in multiple biological samples, the chloride selective electrode comprising:
an inert substrate;
a chloride sensitive membrane formed on the inert substrate, wherein the chloride sensitive membrane is provided with a plurality of quaternary functional groups, and wherein the chloride sensitive membrane comprises:
an epoxide-based matrix dispensed on the inert substrate, wherein the epoxide-based matrix comprises an epoxy resin having a predetermined number of epoxide groups per molecule;
a mixture of an amino compound and an activator dispensed onto a surface of the epoxide-based matrix, wherein the amino compound and activator are present in the mixture in a stoichiometric amount relative to the number of epoxide groups in the epoxide-based matrix, and wherein the stoichiometric amount is in a range of from about 0.5:1 to about 1.5:1, and wherein the mixture comprises reactive species; and
wherein the chloride sensitive membrane is stable for at least 14 days upon exposure to at least one biological sample.
