ZirChrom-WAX - 5µm

ZirChrom-WAX cross-linked polyethyleneimine-coated zirconia for weak anion-exchange. High anion-exchange capacity that can be controlled by the amount of polymer deposited on the porous zirconia substrate. Useful for the separation of bio-molecules such as nucleotides, nucleosides, oligonucleotides, oligodeonucleotides, amino acids, peptides and proteins.

• Stable from pH 3-9
• Efficient weak anion-exchanger useful for inorganic and organic anions
• 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.
