Used in analytical chemistry as a calibration standard for instruments like atomic absorption spectrometers and ICP-MS to ensure accurate detection of strontium levels in environmental, biological, and industrial samples. Commonly applied in water quality testing to monitor strontium contamination in drinking water and wastewater. Employed in geological studies to analyze rock and mineral compositions, especially in strontium isotope ratio measurements for dating rocks and understanding sediment sources. Utilized in nutritional and clinical research to assess strontium metabolism in bone tissues, supporting studies on osteoporosis treatments. Also used in the electronics industry for quality control in the production of ceramic materials and phosphors.
