Catalog Number - 59034-15P

Axis Cyano™ is a versatile cyanopropyl HPLC stationary phase that provides unique selectivity for analytes that may not be adequately resolved on conventional C18 columns. Manufactured on high-purity silica with a bonded 3-carbon ligand terminating in a cyano functional group, this stationary phase has been a trusted choice in analytical laboratories for many years. Its moderate polarity makes it suitable for a wide range of reversed phase applications while offering different retention characteristics than traditional alkyl-bonded phases.

59034-15P is a 150 mm x 4.6 mm ID analytical column packed with 5 µm, 100Å Axis Cyano particles. The 150 mm length provides an excellent balance between resolution and analysis time, making it suitable for routine analytical methods, quality control testing, and method development. The industry-standard 4.6 mm ID format typically operates at approximately 1.0–2.0 mL/min on conventional HPLC systems, while the 5 µm particle size offers reliable efficiency with moderate system backpressure.

This column is an excellent alternative for methods specifying USP L10 columns. The cyano stationary phase is commonly used for polar and neutral compounds in reversed phase chromatography and typically exhibits shorter retention times and faster column equilibration than unmodified silica columns. Supplied and tested in reversed phase solvents, this column is optimized for reversed phase operation. Laboratories requiring normal phase cyano applications should select columns specifically packed in normal phase solvents.
