    • Low drift, fast response, high selectivity ratio, good thermal stability and wide operating range
    • Continuous electrical shielding and insulation of internal elements, cable and connector
    • Extremely stable, reproducible readings with a minimum of electrical noise
    • Rapid response time that lowers cost per test
    • Individually tested, serialized to meet GLP requirements and backed by the Fisher Scientific Technical Applications staff

    Combination models

    • Feature a homogenous sensing membrane for wide application, rapid response, minimum sample retention, improved precision, and lower detection limits
    • In glass or epoxy body incorporating sensing and reference cells in a single probe
    Bromide Combination ISE
    • Detects bromide in aqueous solutions (and in some nonaqueous solutions)
    • Useful in testing biological fluids, soils, plants, foods, water, and effluents
    • Method approved by ASTM™
    • Glass body
    Chloride Combination ISE
    • Applications include testing of water/wastewater, soil, dairy and tomato-based food products, meats, vegetables, and research with biomedical fluids
    • Method is ASTM and AOAC approved
    • Glass body
    Cupric Combination ISE
    • Used to determine copper in silicon, petrochemicals, plating water, and wastes
    • Glass body
    Cyanide Combination ISE
    • Measures cyanide ions in aqueous solutions
    • For monitoring in petrochemical and plating processes, water supplies, and manufacturing wastes
    • Epoxy body
    Fluoride Combination ISE
    • Determines F- concentration down to 1 x 10-6M (0.02ppm)
    • Applications include analyses of water, wastewater, stack gases, explosives, etching baths, research with biological fluids and tissues, beverages, detergents
    • Method has ASTM and EPA approval
    • Glass body
    Lead Combination ISE
    • Determines lead in organic compounds, biological samples, water/waastewater
    • Glass body
    Silver/Sulfide Combination ISE
    • Determines silver and sulfide in water and pulping liquors
    • Glass body

    Cyanide solutions are highly toxic; use a pipet bulb when preparing them. Acidic cyanide solutions produce hydrogen cyanide; procedures with these must be done in a fume hood. Measurements above 10-3M should be done infrequently, as the cyanide ion slowly erodes the sensing membrane.
