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 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.
Aviator C18 HL (High Load) is a high surface area, high carbon load phase, leading to increased retention and loading compared to Aviator C18. Availability of particle sizes up to 20 microns ensures easy scale-up for preparative and process scale applications.
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.
