TSKgel ODS-80Tm
TSKgel ODS-80Tm is based on a high-purity, metalfree silica with 10 nm pore size bonded to C18 (ODS) groups resulting in an effective pore size of 8 nm (80 Å). High endcapping of the TSKgel ODS-80TM phase with a monolayer of TMS groups shields the silica surface from participating in solute retention through ionic interaction.
