Ion Selective Electrodes (ISE) Ammonia

For ammonia and carbon dioxide analyses; tough, chemical-resistant body; permanently bonded membrane/cap assembly—no difficult user assembly required

 

Preassembled, pretested membrane/cap unit

• Assures optimum membrane tension and alignment, with no-leak operation
• Membrane is much less susceptible to surfactant deterioration: use it for extended periods in more varied solution types—wastewater samples, process streams
• Noncrystallizing fill solution won't impede performance or cause membrane rupture
• With 39 in. (1m) lead

Features

• Tough, chemical-resistant body
• Bonded membrane/cap assembly
• Continuous electrical shielding and insulation of internal elements, cable and connectors
• Extremely stable, reproducible readings with a minimum of electrical noise
• Lower detection limits than conventional ISEs
• Rapid response time that lowers cost per test
• Individually tested, serialized to meet GLP requirements, and backed by the Fisher Scientific™ Technical Applications staff

Ammonia Combination ISE

• Determines ammonia and ammonium ion concentration in diverse samples
• Applications include sewage effluent, boiler water, industrial wastes, stack gases, food, fertilizers
• Measurements are unaffected by sample color, turbidity or suspended solids
• Gases such as CO₂, SO₂ and H₂S do not interfere
• Method has ASTM and EPA approval

Carbon Dioxide Combination ISE

• Measures carbon dioxide, carbonate and bicarbonate
• Applications include carbonated beverages, wines, groundwater, seawater
