Anion Exchange Chromatography Columns

Print
QA-825
DEAE-825
· Suitable for analyzing relatively high molecular weight compounds: proteins, peptides, DNA, and RNA
· Usable in a wide pH range from pH 2 to 12
· QA-825 fulfills USP-NF L23 requirements
ES-502N 7C · Compared to IEC series columns, polyvinyl alcohol is used as base material and this offers different separation pattern
· Low hydrophobic interaction of proteins allows analysis under mild conditions
