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 80°C, 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.
