C18 Phases: SP-ODS-BP
The ODS-BP Series provides enhanced selectivity and strong retention for hydrophilic and polar compounds that are poorly retained on traditional ODS phases. Our proprietary modification technique avoids the phase collapse effect of the C18 chains typically seen with ODS phases under high water content mobile phase conditions. The ODS-BP Series demonstrates longer lifetime in aqueous eluents and can even be used in pure aqueous conditions.
Typical Applications
Low carbon ODS for hydrophilic & polar compounds
Small Molecules
Fish Oil (EPA)
Synthetic Peptides
Flexibility
ODS-BP Series have enhanced mechanical stability and are suitable for use in DAC columns. Since they are fully endcapped, they show similar selectivity as conventional C18 phases when used with hydrophobic compounds and typical reversed phase eluents for added flexibility.
Proprietary Endcapping
Proprietary trimethylsilyl endcapping groups on the ODS-BP phases shield the C18 bonding to enhance hydrophilicity.
Conventional C18 Phases
The C18 chains are exposed with conventional C18 phases due to less endcapping.
Alanyl Peptides
Typical applications are separations of biomolecules and metabolites such as oligosaccharides, amino acids, small peptides, nucleotides, fish oil / omega-3 fatty acids, and organic acids.
Available in 120, and 200 Å pore sizes and 10 μm, 15 μm, 20 μm, and 50 μm particle sizes

Did you know?
ODS-BP Series show stable baselines and high sensitivity even under neutral pH conditions without buffer or counter-ion additives, making them especially suited for techniques like LC-MS.
