Avantor® ACE® Excel® C18-PFP phase utilizes a specially developed ligand combining a C18 chain with integral PFP functionality. This results in a phase that maintains the hydrophobic, stability and low bleed characteristics of leading C18 phases, yet provides the multiple retention mechanisms of a PFP phase.

• Ultra-high purity, base deactivated silica with exceptional reproducibility
• Ideal for a wide range of analytes differing in hydrophobicity
• Wide range of particle sizes (1.7 to 5 µm) and complementary phases
• Also useful for analytes with π-bonding or electron or proton donor groups
• Ultra-low bleed to ensure LC/MS compatibility
• Suitable for use with 100% aqueous mobile phases
• Method validation kits contain three different batches of the same phase - available on request

Due to its integral pentafluoro phenyl functionality, Avantor® ACE® C18-PFP is also recommended for separations that involve halogenated aromatic compounds, Regio isomers, and those analytes with differing shape constraints.
