Shodex Polymer-Based HPLC Columns – Reversed Phase Chromatography

Shodex Reversed-Phase HPLC Columns are packed with porous polymeric material that remains stable across a pH range of 2–12.

These columns offer an alternative selectivity to the silica-based columns.

Additionally, Shodex offers other polymer-based reversed phase columns without C18 groups, such as the RSpak DE, DM, and DS series, which cater to specific analytical needs.

These columns are usable in a wide pH range from pH 2 to 12 and can be employed with ELSD, CAD, and MS/MS detection methods.
