• Bonded with octadecyl groups
• Providing excellent peak shapes for basic, acidic and neutral compounds
• High hydrophobicity phases
• Good batch to batch, column to column reproducibility
• Stable at pH from 1.5 to 10
• Compatible with 100% aqueous mobile phases

Cnwsil C18 reversed phase columns, packed with high-purity spherical silica, providing superior performance in terms of efficiency and inertness. The low metal content and low residual silanols level help obtain excellent peak shapes for basic, acidic and neutral analyst. High hydrophobicity results in better rentensin for non-polar analytes. High density bonding and double endcapping extend the operating pH range from 1.5 to 10. The columns can be used with 100% aqueous mobile phase compatible C18 without phase collapse.
