The HI4010 fluoride selective electrode is a potentiometric half-cell that housed within an epoxy body. The internal elements are isolated from the sample by a lanthanum fluoride crystal membrane. This solid state sensor requires a separate reference electrode to complete the measurement system.
Hannas solid state half-cell ISEs are designed for use with the HI5315 reference half-cell. The reference half-cell features a cone style junction. The skirted cone geometry of the reference forms the liquid junction with the test solution at the tip of the junction cone, producing a highly stable reference potential and consistent flow rates of electrolyte into the solution. A simple press of the top portion of the ISE makes it easy to empty the electrolyte fill solution and replace when necessary.
For the HI4010 to accurately measure total fluoride concentration, it is important that the pH and ionic strength of the standards and sample be adjusted to a constant value. The total ionic strength adjustment buffer (TISAB) ensures that the solution pH is between pH 5 and 8 and that the activity coefficient is constant. The TISAB solution also preferentially complexes with various metal ions, such as aluminum and iron, which tend to form complexes with fluoride ions. TISAB thus ensures that these metal ions do not interfere, permitting an accurate total fluoride measurement. Measuring all solutions with a constant pH and ionic strength reduces the margin of error between measurements. The HI4010 fluoride solid state ISE can measure from 1M (0.02 mg/L) to saturated F-.
HI4010 Features
- Fixed Sensing Modules - Solid state half-cell ISEs are electrodes that detect free ions in a solution. The highly insoluble, compressed sensing pellet is attached to the HI4010 fluoride half-cell by a fixed sensing module for ease of use.
- Durable Epoxy Body - The probe body of the fluoride half-cell ISE is composed of durable epoxy resin.
- BNC Connection - The HI4010 has a universal BNC connector for easy connection to any benchtop meter with a female BNC probe input.
