ReproSil Star SCX is a silica-based HPLC column functionalized with strong cation exchange (SCX) groups, designed for high-resolution separation of positively charged analytes in pharmaceutical and biotechnical applications. The sulfonic acid functionality provides permanent negative charges, enabling strong and selective interactions with basic compounds such as amines, peptides, and proteins.
The phase is built on high-purity, mechanically stable silica, ensuring excellent efficiency, reproducibility, and column lifetime even under demanding buffer and gradient conditions. ReproSil Star SCX offers reliable retention control, sharp peak shapes, and robust performance, making it a versatile choice for both analytical and preparative ion exchange separations.
ReproSil Star SCX columns from Dr. Maisch HPLC GmbH deliver robust, high-resolution cation-exchange performance – the optimal choice for basic compound analysis in HPLC.
