ZirChrom®-WAX columns offer today's chromatographer the following advantages:

• Efficient weak anion-exchanger useful for inorganic and organic anions. Stable from pH 3-9.
• Useful for the separation of bio-molecules such as nucleotides, nucleosides, oligonucleotides, oligodeonucleotides, amino acids, peptides and proteins.
• High anion-exchange capacity that can be controlled by the amount of polymer deposited on the porous zirconia substrate.
• Different selectivity than silica or polymeric anion-exchangers.
• Does not shrink or swell as a function of anionic strength or organic modifier content of the mobile phase.
• Extremely stable amino phase for normal phase separation of carbohydrates.
