Luna PFP(2) HPLC Columns
The Luna brand of columns and media is more than just a product line from Phenomenex. It is a pledge to provide you with the highest level of satisfaction for your chromatographic goals. The Luna PFP(2) is a pentafluorophenyl phase with strongly electronegative fluorine groups to provide polar selectivity for cationic compounds, while the rigid bonded phase is a good steric selector.
- Extremely discerning for halogenated‚ aromatic and conjugated compounds
- Provides orthogonal selectivity even using traditional reversed phase mobile phase systems
- PFP Ultra pure, metal-free silica (99.99 % purity) (USP: L43)/li>
Long Column Lifetimes and Excellent Performance
Superior Particle Smoothness
4 Mechanisms of Interaction
Luna® PFP(2) columns provide unique selectivity for highly polar compounds, complex natural products, isomers and other closely related compounds. This is achieved by using a propyl linked pentafluorophenyl, which provides multiple retention mechanisms unique to typical reversed phase medias.
- Hydrogen Bonding
- Dipole-Dipole Interactions
- Aromatic and π-π Interactions
- Hydrophobic
A typical alkyl phase (C18‚ C8) achieves selectivity through only 1 mechanism of interaction.
