ISE sensors for bromide (Br⁻) can be applied in a variety of fields due to the importance of bromide in both environmental and industrial processes. Here are some typical uses:

1. Environmental Monitoring:
   • Water quality analysis: Detecting bromide levels in natural waters, wastewater, and groundwater, especially in areas where contamination from industrial or agricultural runoff might occur.
   • Soil testing: Monitoring bromide in agricultural fields, as bromide-based compounds are sometimes used as fumigants.
2. Pharmaceutical and Medical Research:
   • Bromide in drugs: Bromide compounds are used in certain medications, so ISE sensors can monitor bromide levels in pharmaceutical formulations.
   • Biological studies: Measuring bromide concentrations in biological fluids like blood or urine for clinical diagnostics or toxicology.
3. Industrial Applications:
   • Bromide in chemical manufacturing: Bromide is used in various chemical processes, such as the production of flame retardants and other brominated compounds, where precise measurement of bromide ions is required.
   • Oil and gas industry: Bromide is used in drilling fluids for oil extraction, and ISE sensors can be used to monitor its concentration in such applications.
4. Food and Beverage Industry:
   • Bromide as a preservative: While less common today, bromides have been used in food preservation, and their levels may be monitored in food safety testing.
