Anion exchange chromatography (AEX) and cation exchange chromatography (CEX) with strong and weak functional groups for the separation of large biomolecules
IEC QA-825 | IEC DEAE-825 | Asahipak ES-502N 7C
?
Polymer-based anion exchange columns
IEC QA-825
- strong Quaternary Ammonium group
- Suitable for analyzing relatively high molecular weight compounds: proteins, peptides, DNA, and RNA
- Usable in a wide pH range from pH 2 to 12
IEC DEAE-825 | Asahipak ES-502N 7C
- weak Diethylaminoethyl groups
- Asahipak ES-502N 7C: polyvinyl alcohol is used as base material and this offers different separation pattern
- Low hydrophobic interaction of proteins allows analysis under mild conditions
IEC SP-825 | IEC SP-FT 4A | IEC CM-825 | Asahipak ES-502C 7C | CXpak P-421S
