Description
- Particle provides a thin porous shell of high-purity silica surrounding a solid silica core
- 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
- AQ-C18 is a reversed-phase packing that can be used for basic, acidic, and neutral compounds
