摘要: Halide ion-sensitive devices and methods for their use are described. The devices contain a halide ion-permeable overlayer which is superposed on a layer of silver halide and meets certain criteria of thickness and permeability and/or certain compositional criteria. The methods involve bringing a portion of a solution to be analyzed into contact with the halide ion-permeable overlayer and, within a selected time thereafter, measuring the difference in potential between the portion of solution and the silver halide layer.
