Agilent CN Analytical HPLC Col (RP) 4.6 x 150 884950-526

The Agilent ZORBAX CN Analytical HPLC Column (Agilent part 884950-526) is a 4.6 x 150 mm analytical column with a cyano (CN) stationary phase and 5 µm particles for HPLC separations. The CN-modified phase provides alternative selectivity for polar compounds and the column is specified for both reversed‑phase and normal‑phase separations. It is intended for routine analytical workflows where different selectivity from typical C18/C8 phases is required, such as pharmaceutical, environmental and food analyses.

Key Features:

• Manufacturer/Series: Agilent ZORBAX CN (part number 884950-526)
• Dimensions: 4.6 mm inner diameter × 150 mm length
• Particle size: 5 µm (fully porous)
• Pore size: 70 Å
• Phase: Original cyano (CN), endcapped
• Operating pH range: 2–7
• Pressure rating: 400 bar; maximum temperature: 60 °C

Advantages:

• CN phase offers distinct selectivity for polar and moderately polar analytes, providing an alternative to C18/C8 columns.
• Supports both reversed‑phase and normal‑phase modes, giving method flexibility for diverse sample types.
• Endcapped silica and ~7% carbon load reduce silanol interactions for improved peak shape and reproducibility.
• Robust operating window (pH 2–7, up to 60 °C, 400 bar) suitable for standard analytical HPLC instrumentation.
