Equisil SCX is a strong cation exchange (SCX) HPLC column based on fully porous, high-purity silica, functionalized with sulfonic acid groups. This phase provides permanent negative charges, enabling strong electrostatic retention of positively charged (basic) analytes, including amino acids, basic drugs, and small cationic metabolites. Equisil SCX offers robust and reproducible performance in aqueous buffer systems, making it suitable for routine ion-exchange applications in pharmaceutical, food, and environmental laboratories.
Equisil SCX provides strong cation exchange capabilities with reliable retention – ideal for the precise separation of positively charged compounds in diverse analytical workflows.
