NEW - SpeedCore AQUA
Polar Retention and Selectivity
Improve Resolution even at high speed
Provide high efficiency
Excellent Method Development option
SpeedCore® AQUA increases retention of polar analytes over alkyl chain stationary phase particles, leading to a combination of high
efficiency, resolution and sensitivity.
Polar Retention - Water Soluble Vitamins
SpeedCore AQUA columns can resolve closely related compounds such as ascorbic and isoascorbic acid even with highly aqueous simple mobile phase systems. The combination of alkyl chain and polar endcapping on a SpeedCore particle providing selectivity, efficiency and speed.

Retention of polar Water Soluble Vitamins is simplified by the use of a polar-endcapped stationary phase.
The new SpeedCore AQUA stationary phase is designed to help retention of polar analytes. By combining a C18 ligand with a polar endcap, both hydrophobic and hydrophilic species can be retained together.
An example of small polar organic acids highlights the extra retention and selectivity that can be achieved.
Organic acids
The ability to run highly aqueous mobile phases in order to retain small polar molecules without the need to move to HILIC mobile phases or ion-pair reagents can be a real bonus in terms of reproducibility and robustness of a method.
