BULK SILICA

C18 Phases: SP-ODS-RPS

The ODS-RPS Series 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 ODS-RPS Series 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.

Synthetic Peptides

Batch-to-Batch Reproducibility

The ODS-RPS Series 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.

ODS-RPS Series silica gels feature maximum surface coverage and are a workhorse for a wide variety of organic compounds. Carefully controlled full endcapping leads to optimal performance with acidic, basic and chelating compounds.

Available in 60, 100, 120, 200, and 300 Å pore sizes and 10 μm, 15 μm, 20 μm, and 50 μm particle sizes
