C18 Phases: SP-ODS-BP

The ODS-BP Series provides enhanced selectivity and strong retention for hydrophilic and polar compounds, such as peptides, nucleic acids, organic acids, and sugars, 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 a longer lifetime in aqueous elements 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 a range of particle sizes
