  • Anion selective electrodes containing fumed silica
    Patent number: 5421983
    Abstract: This invention relates to enhanced selectivity anion membrane electrodes useful in determining the amount of an anion of interest in a biological sample. The enhanced selectivity anion membrane formulation contains fumed silica, a polymer material, and an anion selective agent. The presence of fumed silica surprisingly minimizes or reduces the effect of interfering substances, such as salicylate which may be present in biological samples and which interfere with the determination of various anions of interest, such as chloride (Cl.sup.31).
