ZirChrom-SAX cross-linked polyethyleneimine-coated zirconia for strong anion-exchange. Useful for the separation of bio-molecules such as nucleotides, nucleosides, oligonucleotides, oligodeoxynucleotides, amino acids, and peptides.
Stable from pH 1-12
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.
