Description

Ascentis™ Express AQ-C18 is a high-speed, high-performance liquid chromatography column based on the Fused-Core™ particle design. AQ-C18 is a reversed-phase packing that can be used for basic, acidic, and neutral compounds.

  • The particle provides a thin porous shell of high-purity silica surrounding a solid silica core
  • Exhibits very high column efficiency due to the shallow diffusion paths in the 0.4 μm thick porous shell and the small overall particle size of 2 μm
  • AQ-C18 is a C18 bonded phase prepared using a proprietary procedure that incorporates a small amount of polar silane which makes the phase resistant to dewetting
  • Dewetting resistance allows users of the AQ-C18 phase to run highly-aqueous (up to 100%) mobile phases
  • The modified C18 phase exhibits similar retention to Ascentis™ Express C18 with a different selectivity, adding a valuable alternative for resolving difficult separations
  • Can be used for basic, acidic, and neutral compounds
