Hanna HI-4107 Chloride Combination ISE Electrode

HI-4107

The HI-4107 is a solid state, combination Ion Selective Electrode (ISE) for the determination of chloride (Cl-) in solution. The silver chloride sensing pellet produces a potential change due to the chloride ion exchange between the inorganic pellet membrane and the sample.

The HI-4107 is a Chloride solid state combination Ion Selective Electrode.

The HI-4107 is ideal for the determination of free chloride ions in emulsified food products, beverages, plants, soils and as an indicator for titration.

The HI-4107 chloride ion selective electrode is a complete potentiometric cell that contains a silver/silver chloride (Ag/AgCl) reference housed within a PEI plastic body with a potassium nitrate electrolyte. The internal elements are isolated from the sample by a compressed silver chloride sensing membrane.

Hanna’s solid state combination ISEs are designed with a cone style junction. The skirted cone geometry of the sensor 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-4107 to measure chloride accurately, it is important that the ionic strength of the standards and sample be adjusted to a high and constant value with the halide ionic strength adjuster (ISA) solution. The halide ISA ensures that the activity coefficient is constant so the concentration of free chloride ions can be measured. Measuring all solutions with a constant ionic strength reduces the margin of error between measurements. The HI-4107 chloride solid state ISE can measure from 50µM (1.8 mg/L) to 1M (35,500 mg/L).
