Shim-pack GIS RP-Shield contains a polar functional group
embedded between silica surface and an octadecyl group,
making it stable in 100% aqueous mobile phases without phase
collapse. The embedded polar functional group is also extremely
base deactivated, which enables the column to provide superior
peak shape for acids.
Shim-pack GIS RP-Shield provides unique selectivity as hydrogen
bonding interactions, making it suitable for separations that
cannot be achieved by other modes, such as hydrophobic
interactions or p-p interactions.
