Certificates of Analysis

Sulphide (S²⁻) ions can be found in water sources, such as groundwater, drinking water and wastewater. Exposure to high concentrations can be damaging for human health, so it is important to monitor and regulate the sulphide concentrations.


Sulphide concentrations are typically measured using an ion-selective electrode (ISE). Hanna can provide a range of electrodes and bench or portable meters suitable for accurate sulphide measurement.
