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 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.
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.
