Shodex Polymer-Based Columns – Reversed Phase Chromatography
Shodex Polymer-Based Columns
Reverse 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.
The Asahipak ODP-50 series, which features C18 functional groups and is commonly used for analyzing non-polar substances in pharmaceuticals, food, and biological samples.
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.
The ODP-50 series fulfills USP L67 requirements, making it a reliable choice for various applications.
For those seeking extra small pore sizes, the RSpak DE-213, DE-413, and DE-613 columns are suitable for analyzing vitamins, preservatives, and organic acids.
