The Selectra® PFPP (pentafluorophenylpropyl) phase interacts strongly with basic, halogenated and nitrogen-containing analytes. The pentafluorophenyl ring exhibits higher selectivity for electron rich aromatic containing molecules as compared to other sorbents. This phase also shows affinity for molecules with fluorine and other halogen atoms. The PFPP phase uses multiple selectivity mechanisms including hydrogen bonding, dipole-dipole, pi-pi overlap, hydrophilic (HILIC), and hydrophobic interactions.
UCT’s Selectra® PFPP is well suited to LC-MS instrumentation due to its reliability and efficiency with acidic mobile phases.
