Chromegabond C18 BD is a specially developed base deactivated C18 material. Excellent peak shapes are obtained, without modifiers, through the use of special organosilanes and ultra pure synthetic silica.
The Aviator line has identical selectivity to ACE HPLC columns. Aviator AQ is a C18 bonded phase with integral polar functionality which is resistant to phase collapse even with 100% aqueous mobile phase. Recommended for applications where 100% aqueous mobile phases are required. Ideal for fast gradients due to rapid re-equilibration properties.
Aviator C4 is the ideal choice for separating polar, moderately polar, and non-polar analytes (including uncharged acids and bases, strong acids or bases in un-ionized form or in ionized form using an ion-pair modifier.) Aviator C4 columns produce better peak shape and column efficiency when separating troublesome compounds.
