C18 Phases: SP-ODS-P

Ideal for synthetic peptides and small molecules, the small pore size of the ODS-P Series offers exceptionally high surface area and high loadability for superior performance for both hydrophilic and hydrophobic compounds. This ultra high purity spherical silica gel series is produced with a strictly controlled manufacturing process resulting in reproducible particle size and pore size distributions.

Typical Applications

Your first choice for synthetic peptides + small molecules

Small Molecules

Synthetic Peptides

Bonding Density

The bonding density provides a selectivity suitable for both hydrophilic and hydrophobic compounds, even enabling the use of 100% aqueous eluents. Our proprietary endcapping technology minimizes residual silanol groups below detectable levels, thereby improving peak symmetry, reducing tailing of basic compounds, and improving chemical robustness.

Loading. Sustained.

The ODS-P Series provides long peak retention combined with high surface area. The 450 m2/g surface area is higher than other 60 Å silica gels. This silica gel product should be your first choice for small molecule and synthetic peptide purification method development.
