Thermo Scientific™ BioBasic™ HPLC columns provide improved performance for biological samples including peptides, proteins, and other biomolecules. The high purity silica and tailored pore sizes provide superior performance in terms of improved resolution, efficiency, reproducibility, and column life.

BioBasic AX Columns utilize a polymeric secondary-tertiary amine (polyethyleneimine) ligand that is bound to a highly pure, base-deactivated silica that provides separation of proteins, peptides, other anionic species, and polar molecules. The polyethyleneimine bonded phase allows for additional chromatographic options, including hydrophilic interaction chromatography (HILIC) — ideal for separation of sugars and other highly polar species. BioBasic AX columns are i
