INFOGRAPHIC: Anatomy of an Ion-Selective Electrode

Posted by Marketing Team on

Anatomy of an Ion-Selective Electrode Cross-section representation of an ISE, consisting of a thin membrane separating the analyte and filling solution. The membrane selectively allows only the intended ions to pass through, creating a potential difference. Anatomy of an Ion-Selective Electrode Text to be included: Cross-section representation of an ISE, consisting of a thin membrane separating the analyte and filling solution. The membrane selectively allows only the intended ions to pass through, creating a potential difference. Selective Ion Transport The movement of ions from high to low concentration through selective binding within the membrane. This process generates a potential difference, crucial for ion detection in ion-selective electrodes. Advantages Linear Response Non-Destructive Non-Contaminating Short Response Time Unaffected by Color or Turbidity Limitations Susceptible to Fouling of proteins or other organic solutes. Interference by Other Ions Limited Shelf Life Dependency on Uncomplexed Ions requiring absence or masking of ligands.

SUMMARY

  • The ion-selective electrodes (ISE) rely on a narrow membrane with a selective function to deliver specific ions. The process causes a slight electrical gradient. The ions migrate through the membrane and go from higher to lower concentration, producing the difference, and creating the basis for a specific detection method.

  • The MSE PRO Electrochemical Sensors covers a broad spectrum of membranes, each offering solutions for various analytical needs.

  • The advantages and limitations show you how to effectively utilize Ion-selective electrodes (ISE) in analytical applications while mitigating potential challenges.
