Ultrasep ES 100 CN

Cyano Column for Versatile Normal-Phase and Reversed-Phase HPLC

Ultrasep ES 100 CN is a silica-based HPLC column with a 100 Å pore size and a cyanopropyl (CN) bonded phase. This stationary phase offers unique polarity-based selectivity and can be operated in both normal-phase and reversed-phase modes, providing excellent flexibility for analytical laboratories.

The CN phase delivers faster elution and orthogonal selectivity compared to traditional C18 or C8 phases, while ensuring reproducibility and sharp peak shapes across a wide range of applications.

Ultrasep ES 100 CN combines polar selectivity with flexible chromatographic modes – the ideal choice for challenging polar compound separations in HPLC.

Key Features:

  • Silica-based stationary phase with 100 Å pore size

  • Cyanopropyl (CN) bonding – USP L10 classification

  • Suitable for both reversed-phase and normal-phase separations

  • Distinct polarity-based selectivity compared to alkyl phases

  • High reproducibility and peak symmetry

  • Available particle size: 5 µm

Typical Applications:

  • Separation of polar and moderately non-polar compounds

  • Normal-phase analysis of lipids, sterols, and organic compounds

  • Orthogonal method development in reversed-phase HPLC

  • Food, pharmaceutical, and environmental testing
