J’sphere ODS packings are based on a spherical, ultra pure, high surface area silica which has a very homogeneous surface providing additional siloxane groups.

• High quality RP columns
• Polarity range created solely by C18 bonding density
• Metabolite recognition
• High siloxane content
• Additional selectivity through H-bonding

J’sphere ODS-H80 is densely covered with polymeric bonded C18 groups yielding a high carbon content and providing a strong, dominant, lipophilic interaction with the nonpolar sites of the sample molecules. The ability to form H-bonding gives additional selectivity, which is essential for difficult separations, such as drug and corresponding metabolite discrimination. Even stereoisomers can be separated by these columns.
