ReproSil Star SAX-3 is a silica-based HPLC column with strong anion exchange functionality and an enlarged pore size of 300 Å, developed for the separation of large biomolecules such as proteins, peptides, and nucleic acids. Compared to the standard ReproSil Star SAX, the wider pore structure of SAX-3 provides improved mass transfer and accessibility for high-molecular-weight analytes, ensuring efficient ion-exchange interactions and sharp peak shapes.
The stationary phase is built on high-purity, mechanically stable silica with quaternary ammonium groups, offering robust retention, excellent reproducibility, and long column lifetime under various buffer and gradient conditions. ReproSil Star SAX-3 is ideally suited for biotechnological and pharmaceutical applications requiring selective and reproducible anion exchange chromatography of macromolecules.
ReproSil Star SAX-3 extends the proven performance of the SAX phase to large biomolecules – the reliable choice for high-resolution anion exchange separations using a 300 Å pore silica matrix.
