Exploit selectivity by adjusting pH


SuperC18™ and SuperPhenylHexyl™ phases

  • Two bonded phases give complementary selectivity for rapid, systematic method development
  • Excellent reproducibility and column lifetime
  • Ultra-inert phases ensure excellent peak shape

ACE UltraCore SuperC18 and SuperPhenylHexyl phases are manufactured using our unique Encapsulated Bonding Technology (EBT™). This technology dramatically increases ligand coverage of the silica surface and effectively eliminates the negative effects of unbonded silanol groups. The higher ligand coverage results in improved inertness, chromatographic performance and stability.


Ultra-Inert Solid-Core Particles

  • 2.5μm and 5μm ultra pure solid-core (superficially porous) particles
