BULK SILICA

C18 Phases: SP-ODS-RPS

The RPS Series ODS is our standard C18 phase and the most popular within the ODS family of products. A wide selection of pore sizes, particle sizes and carbon loading are available so that you can find the most suitable combination for your molecule.

With high acidic resistance, the RPS Series ODS is an ideal choice for the separation of a wide variety of organic compounds including small peptides, oligonucleotides, and organic acids. Additionally, as demand for purified medicinal and recreational cannabis compounds continues to grow, ODS-RPS is ideal for laboratories needing to provide purification services that meet local requirements for controlled product certification.

Typical Applications

Our standard and most popular phase

Small Molecules

Cannabinoids

Synthetic Peptides

Batch-to-Batch Reproducibility

The RPS Series ODS is well-endcapped with exceptional batch-to-batch reproducibility. Its enhanced mechanical stability also makes the series well-suited to dynamic axial compression columns for scale-up.
