The HI-4009 is a solid state, half-cell ion selective electrode (ISE) for the determination of cyanide (CN-) in solution. The silver halide sensing pellet produces a potential change due to the cyanide ion exchange between the inorganic pellet membrane and the sample. The internal sensing elements are housed within a durable epoxy body.

The HI-4009 is ideal for a variety of applications in plating, wastewater, and agriculture.

  • Solid state sensor
  • Detection from 0.026 to 260 mg/L CN-
  • For use with HI-5315 reference half-cell
  • HI-4009 Cyanide Half-Cell ISE information

    Hanna's extended description

    The HI-4009 cyanide selective electrode is a potentiometric half-cell sensor housed within an epoxy body. The internal elements are isolated from the sample by a compressed silver halide sensing 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 HI-4009 to measure cyanide accurately, it is important that the ionic strength of the standards and sample be adjusted to a high and constant value with the cyanide ionic strength adjuster (ISA) solution. The alkaline ISA ensures that the activity coefficient is constant so the concentration of free cyanide ions can be measured. Measuring all solutions with a constant ionic strength reduces the margin of error between measurements. The HI-4009 cyanide solid state ISE can measure from 1µM (0.026 mg/L) to 0.01M (260 mg/L).

    BNC Connection – BNC is one of the most commonly used connector types in pH meters and electrodes. Compatible with any meter or electrode that uses BNC connectors.
