Description

The target analytes include acids, bases, and polar analytes.

  • High-speed, high-performance liquid chromatography column based on the Fused-Core™ particle design.
  • The particle provides a thin porous shell of high-purity silica surrounding a solid silica core.
  • This particle design exhibits very high column efficiency due to the shallow diffusion paths in the 0.6 μm thick porous shell and the small overall particle size of 5 μm.
  • The 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.
  • This resistance to dewetting allows the 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.
  • The AQ-C18 is a reversed-phase packing that can be used for basic, acidic, and neutral compounds.
