General description

Extra stable for low pH mobile phases due to sterically protected phase.

Useful for selectivity in the reversed-phase mode, including π π and dipole-dipole interacting compounds. Can also be used HILIC mode and normal phase chromatography.

Features and Benefits

  • Enhanced stability at low pH
  • Operates in reversed-phase, HILIC, and normal phase modes of chromatography
  • Low MS bleed
  • 100% aqueous compatible
  • Available as 3 μm and 5 μm particles
  • Particle composition: Type B silica gel
  • Particle shape: Spherical
