ELECTRODE FLUORIDE COMBINATION

Description

Features

• 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

• 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

• 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

• Used to determine copper in silicon, petrochemicals, plating water, and wastes
• Glass body

• Measures cyanide ions in aqueous solutions
• For monitoring in petrochemical and plating processes, water supplies, and manufacturing wastes
• Epoxy body

• Determines F^- concentration down to 1 × 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

• Determines lead in organic compounds, biological samples, water/waastewater
• Glass body

• 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.
