Product Definition and Technical Fundamentals
Ion-selective electrode (ISE) sensors represent a class of analytical devices engineered to measure the concentration of specific ions within a solution. Operating on the principle of potentiometric measurement, these sensors utilize a selective membrane or sensing surface that responds exclusively to the target ion species, generating an electrical potential (voltage) directly proportional to the logarithm of the ion’s concentration, as described by the Nernst equation.
The technical architecture of ISE sensors offers several distinct advantages for analytical applications:
Selectivity: The membrane material is formulated to respond preferentially to the target ion, enabling accurate measurement in complex matrices containing multiple ion species
Simplicity: ISE sensors provide direct measurement without requiring complex sample preparation or sophisticated instrumentation
Real-Time Capability: Continuous measurement capability enables real-time monitoring of ion concentration changes, supporting process control applications
Portability: Compact sensor designs enable field-based measurements, expanding applications beyond traditional laboratory settings
Common ISE sensor applications target ions including hydrogen (pH), fluoride, chloride, sodium, potassium, calcium, ammonium, nitrate, and others relevant to water quality, agricultural, and industrial applications.
