Chloride

Chloride ions are one of the major inorganic anions in water and wastewater. Although high concentrations of chloride in water are not known to be toxic to humans, its regulation is mainly due to taste. It is essential to monitor chloride concentration in boiler systems to prevent damage of metal parts. In high levels, chloride can corrode stainless steel and be toxic to plant life. Hanna Instruments offers a wide variety of instrumentation for measuring chloride. Products include portable and benchtop pH/ISE meters that can use a solid-state chloride Ion-Selective Electrode (ISE) for direct measurement. In addition, Hanna offers portable photometers, checker colorimeters, and chemical test kits. The argentometric titration for chloride is a very common measurement when determining the sodium content in food. In this titration sodium chloride reacts with silver nitrate to form silver chloride precipitate. The precipitation of chloride results in less free chloride in the sample which is detected by a chloride ISE. A silver ISE is also used as a detector tol sense the free silver ions once all the chloride has been reacted with. The argentometric titration is used in other industries where sodium concentration can be inferred by the chloride that is present and for ones that are looking to determine the concentration of chloride.

Portable Meters

Portable pH/ISE allow the flexibility to perform an ISE measurement with a portable. It is a laboratory measurement that requires the addition of the ISA to fix the ion activity in the sample and the use of a magnetic stirrer to keep the sample homogenous. The portable pH/ISE meter has the ion charge and formula weight pre-programmed for concentration measurements. Also availabe multi-parameter portable meters that measure pH, ORP, dissolved oxygen, conductivity, ammonium, chloride, and nitrate. The multi-parameter portables can be ordered with probes that can also measure turbidity and meters that have built-in GPS for data mapping.

Benchtops

Benchtop pH/ISE meters include a two channel option in which a pH probe can be connected to one channel and the chloride ISE to the other. The benchtop meters have the ion charge and formula weight pre-programmed for use with the chloride ISE. The benchtop meters also have incremental methods pre-programmed including the known addition, known subtraction, analyte addition and analyte subtraction methods.

Electrodes and Probes

The chloride ISE is a solid state sensor that measures free chloride ions in ground water, boiler water, drinking water, and many other applications including in concrete materials testing. This chloride ISE is available as either a single half-cell or combination design  with a reference cell. The ISE is a convenient way to measure chloride. The chloride ISE used with the mulitparameter meter does not use ISA. The activity coefficient is based on typical surface water conductivity values.

Checker HC

Checker HC, like a chemical test kit, is reagent based with a color change based on concentration. The handheld colorimeters, like portable and benchtop instrumentation, use the Beer-Lambert principle to determine the color change. The color change is measured by a photoelectric cell which is more accurate than subjective visual interpretation.

Titrators

Titration systems with precision dosing pumps are available to measure chloride. There are options for titrators with two analog inputs and two dosing pumps. This configuration would allow for a linked titration in which acidity can be measured then chloride. A complete system would include an auto sampler that has additional pumps for the acid reagent to automatically be added when the salt titration is performed.
