Extraction Chromatographic Resin
Sr Resin
Sr Resin is a crown ether-impregnated solid phase extraction (SPE) chromatographic resin, specifically designed for the highly selective separation and enrichment of strontium (Sr). It is also commonly used for Pb/Po and Ba/Ra separation, and widely applied in Sr isotope analysis and radioactive detection in environmental, nuclear industry, geological, and food fields.
Advantages Summary
High Selectivity: Strong specificity for Sr²⁺, with extremely high Ca/Sr separation efficiency.
High Capacity: Suitable for trace to macro Sr separation.
Easy Operation: Adsorption under high acid conditions, elution under low acid conditions, short process, and easy automation.
Strong Matrix Tolerance: Suitable for complex environmental and industrial samples.
