  • Solid state sensor
  • Detection from 0.02 mg/L to saturated F-
  • For use with HI-5315 reference half-cell

The FC301B is a solid state, half-cell Ion Selective Electrode (ISE) for the determination of fluoride (F-) in solution. The lanthanum fluoride crystal membrane produces a potential change due to the fluoride ion exchange between the membrane and the sample. The internal sensing elements are housed within a durable epoxy body. The FC301B is ideal for a variety of applications in drinking water treatment, environmental monitoring, and plating baths.

The FC301B fluoride selective electrode is a potentiometric half-cell 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.

Hanna’s solid state half-cell ISEs are designed for use with the HI-5315 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 FC301B 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 aluminium 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 FC301B fluoride solid state ISE can measure from 1µM (0.02 mg/L) to saturated.
