Cogent NP™ Cyano for Normal Phase in L10 Methods

Most Popular Cyano Column for Normal‑Phase HPLC and USP® L10 Methods

Cogent NP™ Cyano HPLC columns are MICROSOLV’s most popular cyano phase, trusted by laboratories worldwide for normal‑phase (NP) separations, USP® L10 methods, and scalable workflows from analytical to preparative HPLC.

Manufactured using world‑class, high‑purity silica and a proven cyano bonding technology refined over many years, these columns deliver consistent, reliable performance and are regarded as among the finest cyano phases available.

Optimized Cyano Chemistry for Normal‑Phase HPLC

Cogent NP™ Cyano columns are not end‑capped, a design choice that allows them to equilibrate faster than plain silica columns while remaining less retentive. This makes them particularly well suited for gradient elution in normal‑phase HPLC, where excessive retention and long equilibration times can be limiting.

The cyano (CN) bonded phase provides balanced polarity, offering improved selectivity compared to bare silica while maintaining predictable retention behavior across a wide range of analytes.

Packed and Ready for Normal‑Phase Use

Each Cogent NP™ Cyano column is packed and ready for immediate use in normal‑phase HPLC. The column chemistry and packing quality support excellent efficiency, reproducibility, and robustness for both routine analysis and advanced method development.

Wide Range of Particle Sizes and Scalable Formats

Cogent NP™ Cyano columns are available in a wide range of particle sizes, making them suitable for:

• Method development

• Routine analytical testing

• Scale‑up from analytical to preparative separations

This flexibility allows laboratories to maintain consistent selectivity while scaling methods efficiently.

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.
