Chloride combination electrode hanna hi4107 

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.

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).
