Cartridges from the latest generation ExtraBond® Polymeric line are based on the ExtraBond® EB phase. This sorbent is a spherical divinylbenzene polystyrene modified with pyrrolidone.
It has more capacity and surface area than silica-based packings with high recovery and extraction rates. It is a material that provides a balance between hydrophilic and hydrophobic properties and can be used in a pH range from 1 to 14.
The ExtraBond® Polymeric range consists of 4 types of packing materials with differing polarities due to modifications.
