Cyano HPLC Columns packed for Reversed Phase HPLC and useful for USP® L10 Methods and Scalable Separations

Cogent RP™ Cyano HPLC columns are designed for reversed‑phase (RP) chromatography, offering reliable performance, flexible selectivity, and scalability from analytical to preparative HPLC. These columns are suitable for USP® L10 methods and are available in a wide range of particle sizes, making them ideal for both routine analysis and method development.

Manufactured using world‑class, high‑purity silica and a bonding technology refined over many years, Cogent RP™ Cyano columns are recognized as among the finest and most reliable cyano phases available.

Optimized Cyano Chemistry for Reversed‑Phase HPLC

Cogent RP™ Cyano columns are non‑end capped, a design that allows them to equilibrate faster than plain silica columns while remaining less retentive. This balanced retention behavior provides enhanced flexibility when optimizing methods and can be especially advantageous when transitioning between separation modes.

While optimized for reversed‑phase HPLC, the cyano (CN) bonded phase also offers selectivity characteristics that can be beneficial when gradient behavior or reduced retention is desired.

Packed and Ready for Reversed‑Phase Use

Each Cogent RP™ Cyano column is packed and ready for immediate use in reversed‑phase HPLC systems. High packing quality and controlled surface chemistry contribute to excellent efficiency, reproducibility, and long‑term robustness.

Wide Range of Particle Sizes and Scalable Formats

Cogent RP™ Cyano columns are available in multiple particle sizes and formats, allowing laboratories to:

  • Optimize efficiency and resolution

  • Transfer methods confidently

  • Scale separations from analytical to preparative HPLC

This scalability helps maintain consistent selectivity across development, validation, and production workflows.

Column Protection Recommendation

Important: MICROSOLV technical support strongly recommends using the Cogent column filter, which is included with each column, whenever possible. Column filters help protect the column from particulates, extend column lifetime, and maintain consistent chromatographic performance.
