Used in calibration of ion-selective electrodes for accurate measurement of fluoride concentration in water, beverages, and industrial samples. Essential in environmental monitoring to ensure compliance with safety standards for drinking water. Widely applied in quality control laboratories for dental products, such as toothpaste and mouth rinses, to verify fluoride content. Supports analytical procedures in pharmaceuticals and research where precise fluoride levels are critical. Also used in fluoride removal system testing and in geological studies to analyze fluoride in soil and groundwater samples.
