HI-4102 Bromide Combination ISE Electrode
HI-4102
The HI-4102 is a bromide solid state combination ISE ideal for the detection of free Bromide ions.
The HI-4102 is a solid state, combination ion selective electrode (ISE) for the determination of bromide (Br-) in solution. The silver bromide sensing pellet produces a potential change due to the bromide ion exchange between the inorganic pellet membrane and the sample. The internal sensing elements are housed within a durable polyetherimide (PEI) body.
The HI-4102 is ideal for a variety of applications in the pharmaceutical industry, laboratories, drinking water and wastewater treatment, food and beverage production, and in printing processes.
- Solid state sensor
- Skirted cone geometry
- Detection from 0.08 to 79,910 mg/L Br-
The HI-4102 bromide 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 bromide 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-4102 to measure bromide 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 bromide ions can be measured. Measuring all solutions with a constant ionic strength reduces the margin of error between measurements. The HI-4102 bromide solid state ISE can measure from 1µM (0.08 mg/L) to 1M (79,910 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.
