Specifications Related Products References Reviews Description Features and Benefits • Efficient strong anion-exchanger useful for inorganic and organic anions. Stable from pH 1-12. • Ideal for the separation of water-soluble vitamins. • Useful for the separation of bio-molecules such as nucleotides, nucleosides, oligonucleotides, oligodeonucleotides, amino acids and peptides. • High anion-exchange capacity that can be controlled by the amount of polymer deposited on the porous zirconia substrate. • 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. • Thermally stable up to 80oC, which causes different selectivity and high speed separations with lower ionic strength mobile phases. This is very important in the preparation of RNA and DNA samples used for further studies. • Mixed-mode separation modes may be exploited to optimize separations, including Lewis acid-base interactions, hydrophobic interactions and ion-exchange interactions. These modes may be attenuated by adjusting the strong Lewis base content, organic content and ionic strength of the mobile phase, respectively.
