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.
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.
Chromegabond C22 is a highly retentive stationary phase in which hydrocarbon C22 groups are bonded to an ultra-high purity support. The C22 is monomerical bound and is nonendcapped allowing this stationary to be used under wide variety of mobile phase compositions. This phase exhibits even greater hydrophobic interaction than the Chromegabond HC column. The Chromegabond C22 is ideally suited for the separation of triglycerides, PAHs, and steroids.
Chromegabond Amine Columns based on aminopropyl bonding provide superior, reproducible separations and long column life with excellent peak symmetry. Can be used as a weak anion exchange material or a polar stationary phase in normal phase chromatography.
