Summary:OVERCOAT COMPOSITIONS AND ION-SELECTIVE ELECTRODES FOR IONIC ANALYTE DETERMINATIONS An overcoat composition for use in ion-selective electrodes comprises: a) a discontinuous liquid phase comprising an oleophilic solvent dispersed within a continuous phase comprising a hydrophilic binder; b) a complexing agent useful for extracting oleophilic anions; c) a buffer which provides a pH in the range of from about 7.5 to about 9.5 under conditions of use; and d) a nucleating agent. This overcoat composition is particularly useful in ion-selective electrodes for determination of CO2.
