Thermo Fisher Scientific Inc. introduced its Thermo Scientific HyperSep Retain Polymeric SPE range of polymeric SPE products. HyperSep Retain PEP (Polar Enhanced Polymer) is Composed of high-purity, porous polystyrene-divinylbenzene (PS-DVB), modified with hydrophilic functional groups, HyperSep Retain PEP gives retention of polar and non-polar analyte types. The material is stable across the entire pH scale for use with any solution. Eliminating the issues associated with the use of silica-beads, such as sorbent material drying this method of solid phase extraction is suited for separating drugs, metabolites, and peptides in biological fluids, as well as peptides in serum or plasma.
In addition to HyperSep Retain PEP, two further functionalities are offered; HyperSep Retain-CX offers enhanced retention for basic compounds and HyperSep Retain-AX enhanced retention for acidic compounds. All HyperSep Retain chemistries enable fast and easy sample preparation method with high and consistent levels of recovery.
