Supplier: Avantor

DPTMDS deactivated high temperature fused silica retention gap / precolumn. General purpose deactivation for both apolar and polar solvents.

Supplier: Avantor

Saturation columns are placed between the pump and the injector and they saturate the mobile phase with silica, minimising dissolution of the analytical column when working above pH 7.

Supplier: Avantor

CW deactivated fused silica retention gap / precolumn. Deactivation mainly for polar solvents.

Supplier: Avantor

HMDS deactivated high temperature fused silica retention gap / precolumn. Deactivation mainly for apolar solvents.

Supplier: Avantor

This column consists of a highly efficient sulphonated polystyrene resin supplied in the calcium form. It provides excellent separations using only water as the mobile phase.

Supplier: Avantor

Anion exclusion columns are used for the separation of organic acids and weakly ionised anions.
