DNAP II columns are designed specifically to handle complex petroleum samples and separatate based on aromatic ring class even for alky substituted aromatics which are normally more difficult to separate.
Chromegabond SAX (Strong Anion Exchange) Columns based on SAX bonding to provide superior, reproducible separations and long column life with excellent peak symmetry. Can be used in reverse phase and normal phase chromatography.
Chromegabond CN BD is a specially developed base deactivated CN material. Excellent peak shapes are obtained, without modifiers, through the use of special organosilanes and ultra pure synthetic silica.
Chromegasphere SI120 Silica HPLC columns are manufactured from metal free ultra-high purity synthetic silica. TLC solvent systems translate directly to the Chromegasphere SI120 HPLC columns and the high loading capacities permit preparative scale separations.
