Shodex RSpak DE, DM and DS HPLC Columns
Shodex RSpak DE, DM, and DS HPLC columns are polymer-based columns for many different applications. They don’t contain any C18 functional groups but provide the reversed phase separation mechanism by the polymer particle itself. This makes them very stable, so the columns have a very long lifetime. The range includes:
- RSpak DE213, DE-413 and DE-613 – general purpose polymer-based column with similar polarity as ODS columns
- RSpak DM-614 – suitable for the analysis of amino acids and water-soluble vitamins
- RSpak DS-413 and DS-613 – recommended for reversed phase analysis of highly hydrophilic substances that are not well retained by ODS columns
