Raptor Polar X 90Å Series (HILIC & Ion Exchange)

Restek’s Raptor Polar X is a New-to-World, patent pending stationary phase that was specifically designed for and uniquely adept at retaining polar, anionic and hydrophilic compounds. The most commonly used LC retention techniques for polar compounds are HILIC and ion exchange approaches. The Raptor Polar X is a novel phase chemistry that blends these two mechanisms perfectly on a single ligand, allowing the user to access both in a tunable fashion driven by solvent and pH adjustments for “just right retention” for difficult to retain polar compounds.

• Superficially Porous Particle (Core-Shell)
• Mixed Mode (HILIC & IEX) combines HILIC and ion-exchange retention mechanisms together in a single ligand.
• Excellent resolution and separation of a wide variety of polar compounds.
• No time-consuming derivatization or complex ion pairing
• Switch between retention modes with simple mobile phase changes and short equilibration times.
• Ideal for increasing sensitivity and selectivity in LC-MS analyses.
